- In Camunda 8 how long are the messages buffered I saw the default is 1m.
- Where are buffered messages stored is it memory or disk
- Having lot of messages in Workflow will it affect the performance of the cluster in general
Hi @mknarayan1711 - when you publish a message, you can specify a TTL for the buffer (see here and here). I believe the buffered messages are stored on disk, but I admit I am not completely sure; I will ask around to find out more!
Yes, having a lot of buffered messages can begin to affect performance, but there are many, many variables that affect this: how many brokers, what resources are allocated, how you’re configured back pressure handling, etc. It’s hard to guess what sort of impact may be had, but if you’re planning on having a lot of buffered messages, then I would plan on doing some testing and account for it while sizing your environment.
