nsivabalan commented on issue #8132: URL: https://github.com/apache/hudi/issues/8132#issuecomment-1528118945 hey @coffee34 : The code that you pointed out where inserts converted to updates is not applicable to bloom and simple index. Those are meant for few other index types. But for these two indexes, inserts will always go into a new base file and only update can go into log files. From the info provided, we could not get any leads and we don't see any other data loss reports from the community. We do have some reports around global index, but those will surface differently. What you are reporting is completely diff. Can you provide us w/ a full backup of ".hoodie" and write configs. but as of now, we can't think of any reason why such huge data loss can occur. unless you changed the record key / partition path config for instance. Do you happen to know any changes to your pipelines around the time where you see data loss. like any config updates. or anything of those sort. If you have a back up of the file slice in question, we can try to copy them locally(on your end) and trigger compaction and debug whats going on. -- This is an automated message from the Apache Git Service.

nsivabalan commented on issue #8132: URL: https://github.com/apache/hudi/issues/8132#issuecomment-1473201894 got it. thanks. since this is w/ 0.7.0, I am not sure if we had fixed anything on this already. is it feasible to upgrade to 012.2 or 0.13.0 ? you will definitely get all new features, perf etc. -- This is an automated message from the Apache Git Service.

nsivabalan commented on issue #8132: URL: https://github.com/apache/hudi/issues/8132#issuecomment-1465087986 I can't seem to find any reason why this could happen. but don't think 8079 is the issue. that would surface differently. anyways, 0.7.0 is very old. We have come a long way from 0.7.0. We have fixed issues w/ compaction and spark cache invalidation For eg https://github.com/apache/hudi/pull/4753 https://github.com/apache/hudi/pull/4856 but I could not exactly say if these are the issues. But from the timeline provided, I could not reason about why parquet size might reduce. infact number of records reduced by 50% from previous version, even though log file modified just 100 ish records :( -- This is an automated message from the Apache Git Service.
