Types

type CommitOrder 

type CommitOrder int32

CommitOrder is used to designate which of the ShardSessions get used for transactions. 

const (
	// NORMAL is the default commit order.
	CommitOrder_NORMAL CommitOrder = 0
	// PRE is used to designate pre_sessions.
	CommitOrder_PRE CommitOrder = 1
	// POST is used to designate post_sessions.
	CommitOrder_POST CommitOrder = 2
	// AUTOCOMMIT is used to run the statement as autocommitted transaction.
	CommitOrder_AUTOCOMMIT CommitOrder = 3
)

Session objects are exchanged like cookies through various calls to VTGate. The behavior differs between V2 & V3 APIs. V3 APIs are Execute, ExecuteBatch and StreamExecute. All other APIs are V2. For the V3 APIs, the session must be sent with every call to Execute or ExecuteBatch. For the V2 APIs, Begin does not accept a session. It instead returns a brand new one with in_transaction set to true. After a call to Commit or Rollback, the session can be discarded. If you're not in a transaction, Session is an optional parameter for the V2 APIs.
