WL#4818 - Stress testing of PERFORMANCE_SCHEMA
|
|
|
|
The performance schema storage engine is backed by data structures, we
|
|
want to be sure that these data structures are not fragile under
|
|
load.
|
|
|
|
NFS1: 20 threads doing read of performance data (both mutex and
|
|
disk), 5 threads changing what is being instrumented, 25 threads doing
|
|
DML and DDL so that the statistics are updated. Connections should frequently
|
|
disconnect or be KILLed, and reconnect.
|
|
|
|
The database should not crash under any circumstance.
|
|
|
|
How to run:
|
|
|
|
MTR_VERSION=1 ./mtr --stress \
|
|
--stress-suite=perfschema_stress \
|
|
--stress-threads=50 \
|
|
--stress-test-duration=3600
