Hello @ahmedOsman,

as Camunda 7 uses a relational database and performs transaction-based process execution, it is extremely fault-tolerant.

The result of this transactional process execution is that you will never have an invalid state in the Camunda schema.

So killing and restarting pods that contain the process engine is not a problem.

Does this help you?

so Camunda 7 uses relational database to save the state of the process as caching right ? and this is done by zeebe ? and Camunda 7 what do for single point of failure ? how it cover this point ? @jonathan.lukas thanks for a quick respond ^___^

Hello @ahmedOsman ,

no, Zeebe is different and part of Camunda 8.
In Camunda 7, the process engine does not have an explicit name.

The single point of failure is the database that can be snapshotted and replicated in intervals.
