hey @xuzifu666 : do you happened to have the old data intact which had data loss. We would like to root cause this. 0.x release line will be used by lot of OSS users. So, we really wanna get to the bottom of it and fix it. Would greatly appreciate if you an help us triage this. - Do you happened to know when exactly the data loss happens. do you see anything interesting in the timeline around the time the data loss happens. - Is it a single writer or multi-writer. - We do have some suspicion around log record reading that we are chasing. Ref ticket: https://github.com/apache/hudi/issues/10803 But I do not want to bias this one. lets get more info about when exactly data loss is seen. - Are there any task retries in general. I am not familiar w/ flink. But in spark, we might have spark task retries. Are there any such things happening in your pipeline. - Is it happening across all pipelines occasionally or very few pipelines. And if its very few, is there any common characteristics like index type, metadata enabled, etc. in comparison to other pipelines which does not have the data loss issue. - And can you confirm that these pipelines were running w/o any issues w/ older versions of hudi. - Do you happened to reproduce this in a deterministic manner? -- This is an automated message from the Apache Git Service.
