Bug Description
Following is not applicable for PS:
/** We do this many searches before trying to keep the search latch
over calls from MySQL. If we notice someone waiting for the latch, we
again set this much timeout. This is to reduce contention. */
#define BTR_SEA_TIMEOUT 10000
This is a consequence of fix from https:/
So, TRX_ADAPTIVE_
This needs to be documented for PS and/or also remove that column from the I_S table as well since it is obsoleted by the code in row0sel.cc.
========
row->trx_
/* trx_adaptive_
OK(fields[
(longlong) row->trx_
=========
etc. can be elided out as well as a consequence of that.
