[Maria-discuss] [MARIADB 5.5] Profiling truncated
Hello, I'm trying to profile a very long query in production (MariaDB 5.5) using "set session profiling = 1" but when I run the command "show profile for query 1", there is only the only 100 last steps of the query. It's the same checking in "INFORMATION_SCHEMA.PROFILING" I understand the parameter "profiling_history_size" is the maximum number of queries and not the maximum steps stored fora query. => How can I change the number of steps available in the result of the profiling ? Thanks and Regards *Fabien CLERC* <https://www.facebook.com/Yieloo-184624595039051/?fref=ts> <https://twitter.com/intraknow> <https://plus.google.com/+Intraknow?hl=fr> fabien.clerc@yieloo.com ____________________________________________________________ *Editeur de la solution intra'know* Espace performance 3 - Bâtiment Z - 35769 Saint-Grégoire www.intraknow.com <https://www.intra-know.com/yieloo/admin/cciaux/modif/www.intraknow.com> 02 99 55 15 03

It seems this limit is hard-coded and cannot be changed without recompiling MariaDB. Do you really have a query with more than a 100 of states? Could you show what your profile looks like? Regards, Sergei Chief Architect MariaDB and security@mariadb.org
