John Roesler commented on KAFKA-7917: ------------------------------------- After messing with the code for a while, I'm not happy with the trade-offs. Some parts combine cleanly, but others are tightly coupled with different components of Streams, and smashing them all together creates more of a mess. I'm going to close this ticket, and we'll just take this one step at a time by seeing how the codebase looks after https://issues.apache.org/jira/browse/KAFKA-7918 > Streams store cleanup: collapse layers > -------------------------------------- > > Key: KAFKA-7917 > URL: https://issues.apache.org/jira/browse/KAFKA-7917 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: John Roesler > Assignee: John Roesler > Priority: Major > > Following on KAFKA-7916, we can consider collapsing the "streams management > layers" into one. > Right now, we have: > * metering (also handles moving from pojo world to bytes world) > * change-logging > * caching > This is good compositional style, but we also have some runtime overhead of > calling through all these layers, as well as some mental overhead of > understanding how many and which layers we are going through. > Also, there are dependencies between the caching and change-logging layers. > I _think_ it would simplify the code if we collapsed these into one layer > with boolean switches to turn on or off the different aspects. (rather than > wrapping the store with the different layers or not depending on the same > boolean conditions) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
