what is the life cycle of an external task topic

Camunda 7 Topics
1

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).
