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.

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
}

StreamingQueryRunner is a runner used for Queries that are reads and needs to return result in streaming fashion.

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
}

func (*SubscribeQueryRunner) Run 

func (runner *SubscribeQueryRunner) Run(ctx context.Context, tx transaction.Tx, tenant *metadata.Tenant) (*Response, context.Context, error)

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
}

func (*UpdateQueryRunner) Run 

func (runner *UpdateQueryRunner) Run(ctx context.Context, tx transaction.Tx, tenant *metadata.Tenant) (*Response, context.Context, error)
