I was hoping people could comment on how they handle the following
scenerios:
1. Storing the last successfully processed messageId/Offset. Are people
using mysql, redis, etc.? What are the tradeoffs here?
2. How do you handle recovering from an error while processesing a given
event?
There are various scenerioes for #2, like:
1. Do you mark the start of processing a message somewhere, and then update
the status to complete and THEN update the last messaged processed for #1?
2. Do you only mark the status as complete, and not the start of processing
it? I guess this depends of there are intermediate steps and processing
the entire message again would result in some duplicated work right?
