what is the life cycle of an external task topic

Hi,
Do the external task topics get deleted after their usage or they remain indefinitely? We are creating dynamic topics (with a UUID in it’s name) which has only one time usage. So, over a period of time, there would be lot of topics created. Can we delete the topics if they are no more needed?

Thanks,
Pabitra

Hi @Pabitra_Muni and welcome to the forum.

There is no explicit saving of topics in Camunda. For each external task an entry is inserted in the table ACT_RU_EXT_TASK which contains the topic name.
So once there are no external tasks for a given topic anymore, the topic is implicitely gone (and the external task will be removed once it’s completed).
