Symptoms
Slow performance when performing serial or parallel index synchronization on a index with substring_index enabled.
Most of the time is spent in populating the $I table and the $P table via the trigger on $I.
For parallel synchronize, if one parallel slave inserts a token and another parallel slave is blocked from inserting the same token with TX lock, the second parallel slave is also blocked from doing further $I inserts as well.
