Hi, I have a 2 tier flume setup. Tier 1 are agents that accept incomming requests (http source) and put them on (large) file channels. Tier 2 does a lot of processing on these events (with custom interceptors) and a custom sink to store the result in a custom data storage. These tier 2 agents use a (small) memory channel.
The tier 2 interceptors and data storage are all mostly IO bound. I seem to struggle to saturate the tier 2 agents. They are slower than they should be, mostly due to various flume unrelated reasons. However, assume that I would like my tier 2 agents to process more events in parallel. What would be the appropriate way to do this? Do I need multiple avro sinks on the tier 1 agents that map to the same tier 2 avro source? I tried this, and this seems to increase the number of threads on the tier 2 agent that are actually processing events indeed. Is this the way to do it, or not? thanks, Jan
