Why is Seconds_Behind_Source Jumping Between 0 and Seemingly a Random Delay? (Doc ID 1355180.1)

Last updated on JUNE 25, 2021

Applies to:

MySQL Server - Version 4.1 and later
Information in this document applies to any platform.

Goal

Disclaimer: Starting from v8.0, some terms have been deprecated. Older releases will only use the deprecated terminology, and new releases will only use new terminology. Please see https://dev.mysql.com/doc/mysqld-version-reference/en/ for a complete list of those changes, and in which minor versions it happened.

Learn why it sometimes appears like the Seconds_Behind_Source value in the SHOW REPLICA STATUS output is jumping between 0 and a random value and back to 0 again instead of increasing and decreasing in a smooth way.
