Camunda database huge table size

hello,
There is a table in the database called ACT_HI_JOB_LOG. What are the contents of this table and what are their uses in the program?
Is it possible to delete the rows of this table without any problem in accessing the completed processes and the history of the processes and their variables?
I have a problem with the space that this table occupies in the database and that I checked things like History level and cleaning.

The Camunda history tables do require a certain amount of management.
There are detailed strategies on how to deal with your history data in the best practice guild.

Hi @Bagher_Naem,

all executed jobs from the past are saved here. If you don’t need the data anymore, it is save to delete them.

Hope this helps, Ingo

Hi @Niall
To reduce the number of logs, I changed the level. But in the past, for 4 months, about 25 GB of space was occupied by this table for the active level. I have to test how much space the new level takes up.
thanks

Hi @Ingo_Richtsmeier
I deleted all the rows of the table and did not change the history of processes instance and variables.
Thank you.
