hi every body!
we want to use spring boot with camunda.so,generally the main problem is about purging last process instancies.
is it possible to keep old process instance for example some process are done, with out memory or cluster problem?(we had this problem with Oracle BPMS,for example on 800,000 instance we had memory problem,becauce the engine keep them!!!) becauce of,each process instance wants to start,must get value of ram and after it done,does automatically free the ram.
@soheil_qalamkari, you can configure how long the process instance need to be available in the database, Camunda provides this feature out-of-the box solution.
You can refer these docs for how to clear the history data(completed processes).
