Pavel Pereslegin updated IGNITE-26139:
--------------------------------------
Description:
Requirements:
# Support non-autocommit mode using thin client transactions API.
# Support cancellation token using thin client API.
How to implement:
# When executing a query, if autocommit=false and the transaction is not
started - start a new transaction and save it in the JdbcConnection
# JdbcConnection - commit/rollback should commit/rollback this tx.
# When creating a new statement (JdbcStatement) - we should create CancelHandle
(CancelHandle.create()) and save it in statement that will be used to obtain
cancellation token for thin client SQL API.
was:
*NOTE*: this is a preparation step for migrating current JDBC driver
implementation to use thin client SQL API, but the old code for jdbc-managed
transaction (and cancellation correlation token) should not be removed, because
it is still used by current implementation).
