sivabalan narayanan reassigned HUDI-1717: ----------------------------------------- Assignee: Prashant Wason > Metadata Table reader does not show correct view of the metadata > ---------------------------------------------------------------- > > Key: HUDI-1717 > URL: https://issues.apache.org/jira/browse/HUDI-1717 > Project: Apache Hudi > Issue Type: Bug > Reporter: Prashant Wason > Assignee: Prashant Wason > Priority: Blocker > Labels: sev:critical, user-support-issues > > Dataset timeline: C1 C2 C3 Compaction.inflight C4 C5 > Metadata timeline: DC1 DC2 DC3. (DC=deltaCommit) > Assume the dataset timeline has some completed commits (C1, C2 ... C5) and an > async compaction operation in progress. Also assume that the metadata table > is synced only till C3. > The MetadataTableWriter will not sync any more instants to the Metadata Table > since an incomplete instant is present next (Compaction.inflight). > The same sync logic is also used by the MetadataReader to perform the > in-memory merge of timeline. Hence, the reader will also not consider C4 and > C5 thereby providing an incorrect and older view of the FileSlices and > FileGroups. > Any future ingestion into this table MAY insert data into older versions of > the FileSlices which will end up being a data loss when queried. -- This message was sent by Atlassian Jira (v8.3.4#803005)
