Do you receive very many different partitions (days) in one checkpoint cycle (1 min)? In my experience, it's usually in single digits. I'm a little confused about that. > > Of course, I'm not against using LRU, just curious about your case. @hililiwei Partition field data is discrete when read snapshot phase. I write a defective code when use LRU map. Beacause I don't close writer. Thanks for your suggestion. I add memory to avoid oom but checkpoint time is too long. I think cost many time to close writer. I increase checkpoint interval to avoid frequently close writer. Do you have any suggestion? -- This is an automated message from the Apache Git Service.
