Enum mz_coord::session::TransactionOps
source · [−]Expand description
The type of operation being performed by the transaction.
This is needed because we currently do not allow mixing reads and writes in a transaction. Use this to record what we have done, and what may need to happen at commit.
Variants
None
The transaction has been initiated, but no statement has yet been executed in it.
Peeks(T)
This transaction has had a peek (SELECT
, TAIL
) and must only do other peeks.
Tail
This transaction has done a TAIL and must do nothing else.
Writes(Vec<WriteOp>)
This transaction has had a write (INSERT
, UPDATE
, DELETE
) and must only do
other writes.
