Service Update 2021-10-13

New Features

Bug Fixes

This parameter is updated by InnoDB automatically when innodb_adaptive_max_sleep_delay is set. Now, we no longer treat automatic changes to innodb_thread_sleep_delay as a new configuration.
  • Fixed y-axis issue on charts where we were not appropriately subdividing for small ranges
  • Fixed issue where we would incorrectly display an error message suggesting that users' agents have been disconnected if they stayed on the database overview page for too long.
