Pavel Pereslegin updated IGNITE-26139:
--------------------------------------
Description:
Requirements:
# Support non-autocommit mode using thin client transactions API.
# Support cancellation token using thin client API.
Basically what we need to do is the following:
1. When executing a query, if autocommit=false and the transaction is not
started - start a new transaction and save it in the JdbcConnection
2. JdbcConnection - commit/rollback should commit/rollback this tx.
3. 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.
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.
