relates to MXS-3353 Tee filter loses statements if branch... Closed

 Description   

Tee filter seems to work asynchronously. With a too high pace tee filter looses some statements.
It would be nice to make tee filter switchable to synchronous working as well so it works more reliable in certain scenarios:

  • Simulate a Push Replication from a secure zone to a non-secure zone (vs. M/S replication).
  • Copy production traffic to QA/testing system
  • Testing/comparing an old and a new MariaDB server version
  • Testing/comparing MySQL and MariaDB during a migration phase to MariaDB

You could try and see if the mirror router from the experimental module package would work as a substitute for this.

Adding limited support for this into the tee filter turns out to be relatively straightforward for 6.2.
