func (*SessionManager) Create ¶
func (sessMgr *SessionManager) Create(ctx context.Context, trackVerInOwnTxn bool, instantVerTracking bool, track bool) (*QuerySession, error)
Create returns the QuerySession after creating all the necessary elements that a query execution needs. It first creates or get a tenant, read the metadata version and based on that reload the tenant cache and then finally create a transaction which will be used to execute all the query in this session.
func (*SessionManager) CreateReadOnlySession ¶
func (sessMgr *SessionManager) CreateReadOnlySession(ctx context.Context) (*ReadOnlySession, error)
func (*SessionManager) Execute ¶
func (sessMgr *SessionManager) Execute(ctx context.Context, runner QueryRunner, req *ReqOptions) (*Response, error)
Execute is responsible to execute a query. In a way this method is managing the lifecycle of a query. For implicit transaction everything is done in this method. For explicit transaction, a session may already exist, so it only needs to run without calling Commit/Rollback.

type Streaming ¶
type Streaming interface { api.Tigris_ReadServer }
Streaming is a wrapper interface for passing around for streaming reads
type StreamingQueryRunner ¶
type StreamingQueryRunner struct { *BaseQueryRunner // contains filtered or unexported fields }

func (*StreamingQueryRunner) ReadOnly ¶
func (runner *StreamingQueryRunner) ReadOnly(ctx context.Context, tenant *metadata.Tenant) (*Response, context.Context, error)
ReadOnly is used by the read query runner to handle long-running reads. This method operates by starting a new transaction when needed which means a single user request may end up creating multiple read only transactions.
func (*StreamingQueryRunner) Run ¶
func (runner *StreamingQueryRunner) Run(ctx context.Context, tx transaction.Tx, tenant *metadata.Tenant) (*Response, context.Context, error)
Run is responsible for running the read in the transaction started by the session manager. This doesn't do any retry if we see ErrTransactionMaxDurationReached which is expected because we do not expect caller to do long reads in an explicit transaction.
type SubscribeQueryRunner ¶
type SubscribeQueryRunner struct { *BaseQueryRunner // contains filtered or unexported fields }
type SubscribeStreaming ¶
type SubscribeStreaming interface { api.Tigris_SubscribeServer }
type TxListener ¶
type TxListener interface { // OnPreCommit is called before committing the transaction. This means this method is useful when an operation needs // to guarantee transaction atomicity. Error returned by this method will roll back the user transaction. OnPreCommit(context.Context, *metadata.Tenant, transaction.Tx, kv.EventListener) error // OnPostCommit is called after committing the transaction. This means the transaction is complete and any post // activity can happen as part of this implementation. OnPostCommit(context.Context, *metadata.Tenant, kv.EventListener) error // OnRollback is called when the user transaction is rolled back. OnRollback(context.Context, *metadata.Tenant, kv.EventListener) }
TxListener allows listening to a transaction outcome and process the events that is passed in the param accordingly.
type UpdateQueryRunner ¶
type UpdateQueryRunner struct { *BaseQueryRunner // contains filtered or unexported fields }
