feat: concurrent transactions on emulator#1578
Merged
Conversation
The JDBC driver now supports running multiple concurrent transactions on the emulator using a single thread. The emulator still only supports one read/write transaction per database at any time, but the JDBC driver works around this by manually setting a Savepoint after each statement, and using that Savepoint to automatically resume the transaction when it has been aborted by the emulator.
