…3040) * TxThrottler support for transactions outside BEGIN/COMMIT This change allows the TxThrottler to throttle requests sent outside of explicit transactions (i.e. explicit BEGIN/COMMIT blocks) when configured to do so via a new config flag. Otherwise, it preserves the current/default behavior of only throttling transactions inside BEGIN/COMMIT. In addition, when this flag is passed, and because the call to throttle is done in a context in which the execution plan is already known, this change uses the plan type to make sure that throttling is triggered only when the query being executed is INSERT/UPDATE/DELETE/LOAD, so that SELECTs and others no longer get throttled unnecessarily, as they do not contribute to increasing replication lag, which is what the TxThrottler aims at controlling. Signed-off-by: Eduardo J. Ortega U <[email protected]> * Fix e2e flag tests & TxThrottler unit test Signed-off-by: Eduardo J. Ortega U <[email protected]> * Throttle auto-commit statements in QueryExecutor instead of TxPool This changes where we call the transaction throttler: 1. Statements in `BEGIN/COMMIT` blocks keep being throttled in `TabletServer.begin()`. 2. Additionally, throttling is added in QueryExecutor.execAutocommit() and `QueryExecutor.execAsTransaction()`. We also change things so that throttling in this new case is not opt-in via configuration flag but instead is the new and only behavior. Finally, we remove some previously added changes to example scripts that had been added with the intention of testing and are not part of the PR. Signed-off-by: Eduardo J. Ortega U <[email protected]> * Adds test cases for QueryExecutor.Execute() with TxThrottle throttling To make unit testing simple here, we separated the interface and implementation of the TxThrottle, and simply used a mock implementation of the interface in the tests.
