Vitess 6.0.20-20200525 Patch Update

on GitHub

This issue addresses a regression in vtgate performance, which was significant enough that it was decided to backport to the release branch. In addition to this bug fix, there remains a known issue where XtraBackup is not compatible with MySQL 8.0.20. Percona is aware of the issue, and there are no known fixes at this point in time.

Bugs Fixed

• Vtgate: a performance regression was identified as part of the refactoring of vtgate's executor. The executor now maintains a cached copy of the vschema. #6220 #6203
