Constants ¶
const ( FlowNotStarted flowStatus = iota FlowRunning FlowFinished )
Flow status indicators.
const MinAcceptedVersion = 3
MinAcceptedVersion is the oldest version that the server is compatible with; see above.
const Version = 3
Version identifies the distsqlrun protocol version.
This version is separate from the main CockroachDB version numbering; it is only changed when the distsqlrun API changes.
The planner populates the version in SetupFlowRequest. A server only accepts requests with versions in the range MinAcceptedVersion to Version.
Is is possible used to provide a "window" of compatibility when new features are added. Example:
- we start with Version=1; distsqlrun servers with version 1 only accept requests with version 1.
- a new distsqlrun feature is added; Version is bumped to 2. The planner does not yet use this feature by default; it still issues requests with version 1.
- MinAcceptedVersion is still 1, i.e. servers with version 2 accept both versions 1 and 2.
- after an upgrade cycle, we can enable the feature in the planner, requiring version 2.
- at some later point, we can choose to deprecate version 1 and have servers only accept versions >= 2 (by setting MinAcceptedVersion to 2).

Functions ¶
func ColumnMutationFilter ¶
func ColumnMutationFilter(m sqlbase.DescriptorMutation) bool
ColumnMutationFilter is a filter that allows mutations that add or drop columns.
func CompareEncDatumRowForMerge ¶
func CompareEncDatumRowForMerge( lhs, rhs sqlbase.EncDatumRow, leftOrdering, rightOrdering sqlbase.ColumnOrdering, da *sqlbase.DatumAlloc, ) (int, error)
CompareEncDatumRowForMerge EncDatumRow compares two EncDatumRows for merging. When merging two streams and preserving the order (as in a MergeSort or a MergeJoin) compare the head of the streams, emitting the one that sorts first. It allows for the EncDatumRow to be nil if one of the streams is exhausted (and hence nil). CompareEncDatumRowForMerge returns 0 when both rows are nil, and a nil row is considered greater than any non-nil row. CompareEncDatumRowForMerge assumes that the two rows have the same columns in the same orders, but can handle different ordering directions. It takes a DatumAlloc which is used for decoding if any underlying EncDatum is not yet decoded.
func ConvertBackfillError ¶
func ConvertBackfillError(tableDesc *sqlbase.TableDescriptor, b *client.Batch) error
ConvertBackfillError returns a cleaner SQL error for a failed Batch.
func DrainAndClose ¶
func DrainAndClose(ctx context.Context, dst RowReceiver, cause error, srcs ...RowSource)
DrainAndClose is a version of DrainAndForwardMetadata that drains multiple sources. These sources are assumed to be the only producers left for dst, so dst is closed once they're all exhausted (this is different from DrainAndForwardMetadata).
If cause is specified, it is forwarded to the consumer before all the drain metadata. This is intended to have been the error, if any, that caused the draining.
srcs can be nil.
All errors are forwarded to the producer.
func DrainAndForwardMetadata ¶
func DrainAndForwardMetadata(ctx context.Context, src RowSource, dst RowReceiver)
DrainAndForwardMetadata calls src.ConsumerDone() (thus asking src for draining metadata) and then forwards all the metadata to dst.
When this returns, src has been properly closed (regardless of the presence or absence of an error). dst, however, has not been closed; someone else must call dst.ProducerDone() when all producers have finished draining.
It is OK to call DrainAndForwardMetadata() multiple times concurrently on the same dst (as RowReceiver.Push() is guaranteed to be thread safe).
TODO(andrei): errors seen while draining should be reported to the gateway, but they shouldn't fail a SQL query.
func GeneratePlanDiagram ¶
GeneratePlanDiagram generates the json data for a flow diagram. There should be one FlowSpec per node. The function assumes that StreamIDs are unique across all flows.
func GeneratePlanDiagramWithURL ¶
GeneratePlanDiagramWithURL generates the json data for a flow diagram and a URL which encodes the diagram. There should be one FlowSpec per node. The function assumes that StreamIDs are unique across all flows.
func GetAggregateInfo ¶
func GetAggregateInfo( fn AggregatorSpec_Func, inputType sqlbase.ColumnType, ) ( aggregateConstructor func(*parser.EvalContext) parser.AggregateFunc, returnType sqlbase.ColumnType, err error, )
GetAggregateInfo returns the aggregate constructor and the return type for the given aggregate function when applied on the given type.
func IndexMutationFilter ¶
func IndexMutationFilter(m sqlbase.DescriptorMutation) bool
IndexMutationFilter is a filter that allows mutations that add indexes.
func ProcessInboundStream ¶
func ProcessInboundStream( ctx context.Context, stream DistSQL_FlowStreamServer, firstMsg *ProducerMessage, dst RowReceiver, ) error
ProcessInboundStream receives rows from a DistSQL_FlowStreamServer and sends them to a RowReceiver. Optionally processes an initial StreamMessage that was already received (because the first message contains the flow and stream IDs, it needs to be received before we can get here).
func RegisterDistSQLServer ¶
func RegisterDistSQLServer(s *grpc.Server, srv DistSQLServer)
func SetFlowRequestTrace ¶
func SetFlowRequestTrace(ctx context.Context, req *SetupFlowRequest) error
SetFlowRequestTrace populates req.Trace with the context of the current Span in the context (if any).
func WriteResumeSpan ¶
func WriteResumeSpan( ctx context.Context, db *client.DB, id sqlbase.ID, origSpan roachpb.Span, resume roachpb.Span, mutationIdx int, ) error
WriteResumeSpan writes a checkpoint for the backfill work on origSpan. origSpan is the span of keys that were assigned to be backfilled, resume is the left over work from origSpan.

type AggregatorSpec ¶
type AggregatorSpec struct { // The group key is a subset of the columns in the input stream schema on the // basis of which we define our groups. GroupCols []uint32 `protobuf:"varint,2,rep,packed,name=group_cols,json=groupCols" json:"group_cols,omitempty"` Aggregations []AggregatorSpec_Aggregation `protobuf:"bytes,3,rep,name=aggregations" json:"aggregations"` }
AggregatorSpec is the specification for an "aggregator" (processor core type, not the logical plan computation stage). An aggregator performs 'aggregation' in the SQL sense in that it groups rows and computes an aggregate for each group. The group is configured using the group key. The aggregator can be configured with one or more aggregation functions.
The "internal columns" of an Aggregator map 1-1 to the aggregations.

AlgebraicSetOpSpec is a specification for algebraic set operations currently only the EXCEPT ALL set operation, but extensible to other set operations. INTERSECT ALL is implemented with HashJoinerSpec, and UNION ALL with a no-op processor. EXCEPT/INTERSECT/UNION use a DISTINCT processor at the end. The two input streams should have the same schema. The ordering of the left stream will be preserved in the output stream.

BackfillerSpec is the specification for a "schema change backfiller". The created backfill processor runs a backfill for the first mutations in the table descriptor mutation list with the same mutation id and type. A backfiller processor performs KV operations to retrieve rows for a table and backfills the new indexes/columns contained in the table descriptor. It checkpoints its progress by updating the table descriptor in the database, and doesn't emit any rows nor support any post-processing.

HashJoinerSpec is the specification for a hash join processor. The processor has two inputs and one output.
The processor works by reading the entire right input and putting it in a hash table. Thus, there is no guarantee on the ordering of results that stem only from the right input (in the case of RIGHT_OUTER, FULL_OUTER). However, it is guaranteed that results that involve the left stream preserve the ordering; i.e. all results that stem from left row (i) precede results that stem from left row (i+1).
The "internal columns" of a HashJoiner (see ProcessorSpec) are the concatenation of left input columns and right input columns. If the left input has N columns and the right input has M columns, the first N columns contain values from the left side and the following M columns contain values from the right side.

type MergeJoinerSpec ¶
type MergeJoinerSpec struct { // The streams must be ordered according to the columns that have equality // constraints. The first column of the left ordering is constrained to be // equal to the first column in the right ordering and so on. The ordering // lengths and directions must match. // In the example above, left ordering describes C1+,C2- and right ordering // describes C5+,C4-. LeftOrdering Ordering `protobuf:"bytes,1,opt,name=left_ordering,json=leftOrdering" json:"left_ordering"` RightOrdering Ordering `protobuf:"bytes,2,opt,name=right_ordering,json=rightOrdering" json:"right_ordering"` // "ON" expression (in addition to the equality constraints captured by the // orderings). Assuming that the left stream has N columns and the right // stream has M columns, in this expression ordinal references @1 to @N refer // to columns of the left stream and variables @(N+1) to @(N+M) refer to // columns in the right stream. OnExpr Expression `protobuf:"bytes,5,opt,name=on_expr,json=onExpr" json:"on_expr"` Type JoinType `protobuf:"varint,6,opt,name=type,enum=cockroach.sql.distsqlrun.JoinType" json:"type"` }
MergeJoinerSpec is the specification for a merge join processor. The processor has two inputs and one output. The inputs must have the same ordering on the columns that have equality constraints. For example:
SELECT * FROM T1 INNER JOIN T2 ON T1.C1 = T2.C5 AND T1.C2 = T2.C4
To perform a merge join, the streams corresponding to T1 and T2 must have the same ordering on columns C1, C2 and C5, C4 respectively. For example: C1+,C2- and C5+,C4-.
The "internal columns" of a MergeJoiner (see ProcessorSpec) are the concatenation of left input columns and right input columns. If the left input has N columns and the right input has M columns, the first N columns contain values from the left side and the following M columns contain values from the right side.

type MultiplexedRowChannel ¶
type MultiplexedRowChannel struct {
// contains filtered or unexported fields
}
MultiplexedRowChannel is a RowChannel wrapper which allows multiple row producers to push rows on the same channel.

type MutationFilter ¶
type MutationFilter func(sqlbase.DescriptorMutation) bool

type NoMetadataRowSource ¶
type NoMetadataRowSource struct {
// contains filtered or unexported fields
}
NoMetadataRowSource is a wrapper on top of a RowSource that automatically forwards metadata to a RowReceiver. Data rows are returned through an interface similar to RowSource, except that, since metadata is taken care of, only the data rows are returned.
The point of this struct is that it'd be burdensome for some row consumers to have to deal with metadata.
func MakeNoMetadataRowSource ¶
func MakeNoMetadataRowSource(src RowSource, sink RowReceiver) NoMetadataRowSource
MakeNoMetadataRowSource builds a NoMetadataRowSource.
func (*NoMetadataRowSource) NextRow ¶
func (rs *NoMetadataRowSource) NextRow() (sqlbase.EncDatumRow, error)
NextRow is analogous to RowSource.Next. If the producer sends an error, we can't just forward it to metadataSink. We need to let the consumer know so that it's not under the impression that everything is hunky-dory and it can continue consuming rows. So, this interface returns the error. Just like with a raw RowSource, the consumer should generally call ConsumerDone() and drain.
type NoopCoreSpec ¶
type NoopCoreSpec struct { }
NoopCoreSpec indicates a "no-op" processor core. This is used when we just need post-processing or when only a synchronizer is required (e.g. at the final endpoint).

Output []OutputRouterSpec `protobuf:"bytes,3,rep,name=output" json:"output"` }
Each processor has the following components:
one or more input synchronizers; each one merges rows between one or more input streams;
a processor "core" which encapsulates the inner logic of each processor;
a post-processing stage which allows "inline" post-processing on results (like projection or filtering);
one or more output synchronizers; each one directs rows to one or more output streams.
== Internal columns ==
The core outputs rows of a certain schema to the post-processing stage. We call this the "internal schema" (or "internal columns") and it differs for each type of core. Column indices in a PostProcessSpec refers to these internal columns. Some columns may be unused by the post-processing stage; processor implementations are internally optimized to not produce values for such unneded columns.

type RowReceiver interface { // Push sends a record to the consumer of this RowReceiver. Exactly one of the // row/meta must be specified (i.e. either row needs to be non-nil or meta // needs to be non-Empty()). May block. // // The return value indicates the current status of the consumer. Depending on // it, producers are expected to drain or shut down. In all cases, // ProducerDone() needs to be called (after draining is done, if draining was // requested). // // The sender must not modify the row after calling this function. // // After DrainRequested is returned, it is expected that all future calls only // carry metadata (however that is not enforced and implementations should be // prepared to discard non-metadata rows). If ConsumerClosed is returned, // implementations have to ignore further calls to Push() (such calls are // allowed because there might be multiple producers for a single RowReceiver // and they might not all be aware of the last status returned). // // Implementations of Push() must be thread-safe. Push(row sqlbase.EncDatumRow, meta ProducerMetadata) ConsumerStatus // ProducerDone is called when the producer has pushed all the rows and // metadata; it causes the RowReceiver to process all rows and clean up. // // ProducerDone() cannot be called concurrently with Push(), and after it // is called, no other method can be called.

At most one of the return values will be non-empty. Both of them // can be empty when the RowSource has been exhausted - no more records are // coming and any further method calls will be no-ops. // // A ProducerMetadata record may contain an error. In that case, this // interface is oblivious about the semantics: implementers may continue // returning different rows on future calls, or may return an empty record // (thus asking the consumer to stop asking for rows). In particular, // implementers are not required to only return metadata records from this // point on (which means, for example, that they're not required to // automatically ask every producer to drain, in case there's multiple // producers). Therefore, consumers need to be aware that some rows might have // been skipped in case they continue to consume rows. Usually a consumer // should react to an error by calling ConsumerDone(), thus asking the // RowSource to drain, and separately discard any future data rows. Next() (sqlbase.EncDatumRow, ProducerMetadata) // ConsumerDone lets the producer know that we will not need any more data // rows. The producer is expected to start draining and only send metadata // rows. // // May block. If the consumer of the source stops consuming rows before // Next indicates that there are no more rows, ConsumerDone() and/or // ConsumerClosed() must be called; it is a no-op to call these methods after // all the rows were consumed (i.e. after Next() returned an empty row). ConsumerDone() // ConsumerClosed informs the producer that the consumer will not be reading // any more rows. The producer is expected to shut down without sending // anything else. // // Like ConsumerDone(), if the consumer of the source stops consuming rows // before Next indicates that there are no more rows, ConsumerDone() and/or // ConsumerClosed() must be called; it is a no-op to call these methods after // all the rows were consumed (i.e. after Next() returned an empty row). ConsumerClosed() }
RowSource is any component of a flow that produces rows that cam be consumed by another component.
type ServerConfig ¶
type ServerConfig struct { log.AmbientContext // DB is a handle to the cluster. DB *client.DB // FlowDB is the DB that flows should use for interacting with the database. // This DB has to be set such that it bypasses the local TxnCoordSender. We // want only the TxnCoordSender on the gateway to be involved with requests // performed by DistSQL. FlowDB *client.DB RPCContext *rpc.Context Stopper *stop.Stopper TestingKnobs TestingKnobs ParentMemoryMonitor *mon.MemoryMonitor Counter *metric.Counter Hist *metric.Histogram // NodeID is the id of the node on which this Server is running. NodeID *base.NodeIDContainer }
ServerConfig encompasses the configuration required to create a DistSQLServer.

SetupSyncFlow sets up a synchoronous flow, connecting the sync response output stream to the given RowReceiver. The flow is not started. The flow will be associated with the given context. Note: the returned context contains a span that must be finished through Flow.Cleanup.
type SetupFlowRequest ¶
type SetupFlowRequest struct { Txn cockroach_roachpb1.Transaction `protobuf:"bytes,1,opt,name=txn" json:"txn"` // Version of distsqlrun protocol; a server accepts a certain range of // versions, up to its own version. See server.go for more details. Version uint32 `protobuf:"varint,5,opt,name=version" json:"version"` // If set, the context of an active tracing span.

type SorterSpec ¶
type SorterSpec struct { OutputOrdering Ordering `protobuf:"bytes,1,opt,name=output_ordering,json=outputOrdering" json:"output_ordering"` // Ordering match length, specifying that the input is already sorted by the // first 'n' output ordering columns, can be optionally specified for // possible speed-ups taking advantage of the partial orderings. OrderingMatchLen uint32 `protobuf:"varint,2,opt,name=ordering_match_len,json=orderingMatchLen" json:"ordering_match_len"` }
SorterSpec is the specification for a "sorting aggregator". A sorting aggregator sorts elements in the input stream providing a certain output order guarantee regardless of the input ordering. The output ordering is according to a configurable set of columns.
The "internal columns" of a Sorter (see ProcessorSpec) are the same as the input columns.

func (m *SorterSpec) Unmarshal(dAtA []byte) error
type StreamDecoder ¶
type StreamDecoder struct {
// contains filtered or unexported fields
}
StreamDecoder converts a sequence of ProducerMessage to rows and metadata records.
Sample usage:
sd := StreamDecoder{} var row sqlbase.EncDatumRow for each message in stream { err := sd.AddMessage(msg) if err != nil { ... } for { row, meta, err := sd.GetRow(row) if err != nil { ... } if row == nil && meta.Empty() { // No more rows in this message. break } // Use <row> ... } }
AddMessage can be called multiple times before getting the rows, but this will cause data to accumulate internally.
func (*StreamDecoder) AddMessage ¶
func (sd *StreamDecoder) AddMessage(msg *ProducerMessage) error
AddMessage adds the data in a ProducerMessage to the decoder.
The StreamDecoder may keep a reference to msg.Data.RawBytes and msg.Data.Metadata until all the rows in the message are retrieved with GetRow.
If an error is returned, no records have been buffered in the StreamDecoder.
func (*StreamDecoder) GetRow ¶
func (sd *StreamDecoder) GetRow( rowBuf sqlbase.EncDatumRow, ) (sqlbase.EncDatumRow, ProducerMetadata, error)
GetRow returns a row received in the stream. A row buffer can be provided optionally.
Returns an empty row if there are no more rows received so far.
A decoding error may be returned. Note that these are separate from error coming from the upstream (through ProducerMetadata.Err).
type StreamEncoder ¶
type StreamEncoder struct {
// contains filtered or unexported fields
}
StreamEncoder converts EncDatum rows into a sequence of ProducerMessage.
Sample usage:
se := StreamEncoder{} for { for ... { err := se.AddRow(...) ... } msg := se.FormMessage(false, nil) // Send out message. ... } msg := se.FormMessage(true, nil) // Send out final message ...
func (*StreamEncoder) AddMetadata ¶
func (se *StreamEncoder) AddMetadata(meta ProducerMetadata)
AddMetadata encodes a metadata message. Unlike AddRow(), it cannot fail. This is important for the caller because a failure to encode a piece of metadata (particularly one that contains an error) would not be recoverable.
Metadata records lose their ordering wrt the data rows. The convention is that the StreamDecoder will return them first, before the data rows, thus ensuring that rows produced _after_ an error are not received _before_ the error.
func (*StreamEncoder) AddRow ¶
func (se *StreamEncoder) AddRow(row sqlbase.EncDatumRow) error
AddRow encodes a message.
func (*StreamEncoder) FormMessage ¶
func (se *StreamEncoder) FormMessage(ctx context.Context) *ProducerMessage
FormMessage populates a message containing the rows added since the last call to FormMessage. The returned ProducerMessage should be treated as immutable.
type StreamEndpointSpec ¶
type StreamEndpointSpec struct { Type StreamEndpointSpec_Type `protobuf:"varint,1,opt,name=type,enum=cockroach.sql.distsqlrun.StreamEndpointSpec_Type" json:"type"` // The ID of this stream. // // For LOCAL streams, both ends of the stream are part of the flow on this // machine (and there must be a corresponding endpoint with the same ID). // // For REMOTE streams, this ID is used in the ProducerHeader when connecting to // the other host. // // For SYNC_RESPONSE streams, the ID is unused. StreamID StreamID `protobuf:"varint,2,opt,name=stream_id,json=streamId,casttype=StreamID" json:"stream_id"` // Serving address for the target host, only used for outgoing REMOTE streams. TargetAddr string `protobuf:"bytes,3,opt,name=target_addr,json=targetAddr" json:"target_addr"` }

type TableReaderSpan ¶
type TableReaderSpan struct { // TODO(radu): the dist_sql APIs should be agnostic to how we map tables to // KVs. The span should be described as starting and ending lists of values // for a prefix of the index columns, along with inclusive/exclusive flags.

LimitHint int64 `protobuf:"varint,5,opt,name=limit_hint,json=limitHint" json:"limit_hint"` }
TableReaderSpec is the specification for a "table reader". A table reader performs KV operations to retrieve rows for a table and outputs the desired columns of the rows that pass a filter expression.
The "internal columns" of a TableReader (see ProcessorSpec) are all the columns of the table. Internally, only the values for the columns needed by the post-processing stage are be populated.
