Optimize logging table
Closed, ResolvedPublic

Description

After T184485 and T189596, there were a lot of deleted rows from the logging table on many wikis. This is a summary of the numbers of rows deleted:

wikidatawiki654029578
commonswiki196956373
frwiki84965885
itwiki43086794
enwiktionary40325873
shwiki38929189
dewiki30377762
viwiki29115179
frwiktionary17784536
nlwiki16476995

While the rows have been already physically deleted, optimizing the tables will reclaim (in some cases) a lot of space and clean up the internal purging log (in some cases, fixing slowdowns. eg. dbstore2* T189596#4160236 ).

While this is not high priority, it would be nice to keep track of the optimized databases/hosts to not work twice.

wikidatawiki and commons were already done as there was a schema change that involved logging table and it rebuilt that table, and it was done right after the deletes finished on that table, so we mark those as done.

As I am altering s7, where frwiktionary and viwiki lives, I will take the opportunity to optimize logging table there

@Marostegui Perhaps the description of this task needs an update after your action.

No because it has not finished across all the hosts of S7 ;)
