# Bug #21280753 MTS MUST BE ABLE HANDLE LARGE PACKETS WITH SMALL
|
|
# SLAVE_PENDING_JOBS_SIZE_MAX
|
|
#
|
|
# To prove the slave applier can apply events that are larger
|
|
# than SLAVE_PENDING_JOBS_SIZE_MAX but only one at a time.
|
|
#
|
|
# Steps to reproduce the issue:
|
|
#
|
|
# 0) Set SLAVE_PENDING_JOBS_SIZE_MAX to a smaller number (1024)
|
|
# and slave_parallel_workers to 2 to make the test easy.
|
|
#
|
|
# 1) Create initial data required for the test
|
|
# (two databases (db1, db2) and two tables (db1.t and db2.t)).
|
|
#
|
|
# 2) Prove that Coordinator will make a big event (bigger in size than
|
|
# SLAVE_PENDING_JOBS_SIZE_MAX) wait for all workers to finish
|
|
# their work (empty their queue) before processing the big event.
|
|
#
|
|
# 3) Prove that when a big event is being processed by a
|
|
# worker, Coordinator will make smaller events to wait.
|
|
#
|
|
# 4) Prove that when a big event is being processed by a
|
|
# worker, Coordinator will make another big event also to wait.
|
|
#
|
|
# 5) Cleanup (drop tables/databases and reset the variables)
|
