Description
ISSUE : Data loss after converting TSM to TSI Indexing .
VERSION : 1.8.0
HOW TO REPRODUCE :
1) Large amount of data should exist in TSM index format.
2) Convert TSM to TSI by below command:
3) Make sure permission are correct:
4)Restart influxdb
BUG : Every time i try to do this with same set of data , Conversion to TSI is successful but only in 1 measurement past 6 months data is not visible when queried. But shard is present with data .
TEMPORARY FIX : Data is present in shard but can only be queried if i change back to TSM indexing.
Contributor guide
Research direction
Start by reproducing the TSM-to-TSI conversion with the same data, permissions, restart, and query sequence described in the issue. Compare query results before and after conversion, and verify that the affected measurement's data remains queryable while the shard is present. Done means the conversion no longer hides the affected data.
