Database size

What is the typical size of an camunda database ?

There’s no database size limitations by camunda. Camunda provides flexibility to persist history data through configurations.

Note that the engine uses Apache MyBatis internally for persistence.

The database schema of the process engine consists of 46 tables. The table names all start with ACT_.

I was actually looking for minimum disk space requirements for the db ?

At the time of Initial database, you can see none of the tables has records. So it would require very less memory, probably it would be in KBs or few MBs.

Hi @saikiran,

It’s hard to predict and depends on these factors:

  • Number of activities and events in the process
  • History level
  • number and type/size of the process variables

Hope this helps, Ingo
