Functions

func NewClient

func NewClient(ctx context.Context) (types.DataCoordClient, error)

NewClient creates a new client instance

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

func (c *Client) AlterIndex(ctx context.Context, req *indexpb.AlterIndexRequest, opts ...grpc.CallOption) (*commonpb.Status, error)

AlterIndex sends the alter index request to IndexCoord.

func (*Client) AssignSegmentID

AssignSegmentID applies allocations for specified Coolection/Partition and related Channel Name(Virtial Channel)

ctx is the context to control request deadline and cancellation req contains the requester's info(id and role) and the list of Assignment Request, which contains the specified collection, partitaion id, the related VChannel Name and row count it needs

response struct `AssignSegmentIDResponse` contains the assignment result for each request error is returned only when some communication issue occurs if some error occurs in the process of `AssignSegmentID`, it will be recorded and returned in `Status` field of response

`AssignSegmentID` will applies current configured allocation policies for each request if the VChannel is newly used, `WatchDmlChannels` will be invoked to notify a `DataNode`(selected by policy) to watch it if there is anything make the allocation impossible, the response will not contain the corresponding result

func (*Client) MarkSegmentsDropped

func (c *Client) MarkSegmentsDropped(ctx context.Context, req *datapb.MarkSegmentsDroppedRequest, opts ...grpc.CallOption) (*commonpb.Status, error)

func (*Client) ReportDataNodeTtMsgs

func (c *Client) ReportDataNodeTtMsgs(ctx context.Context, req *datapb.ReportDataNodeTtMsgsRequest, opts ...grpc.CallOption) (*commonpb.Status, error)

and related message stream positions

ctx is the context to control request deadline and cancellation req contains the collection/partition id to query

response status contains the status/error code and failing reason if any error is returned only when some communication issue occurs

there is a constraint that the `SaveBinlogPaths` requests of same segment shall be passed in sequence

	the root reason is each `SaveBinlogPaths` will overwrite the checkpoint position
 if the constraint is broken, the checkpoint position will not be monotonically increasing and the integrity will be compromised
