Hello,
I had several time an error like
Incorrect key file for table '/tmp/#sql_4aa7_1.MYI'; try to repair it
and I didn't found any really deep info about how MySQL uses and create the
temporary files.
In particular I don't have clear
1) why the format is MYI whlle we do not use any MyISAM table (I have only
Innodb);
2) how can I monitor how their size ( that is not easy because are hidden
files) . I have a tmp folder which is around 5G but probably it is not
enough.
3) best suggestion for tmp tuning
All the best,
Francesco
