There was a problem hiding this comment.
I think there is a ForEachMeasurementName func that exist that does the same as this new method? Any reason to not re-use that one?

Can the conversion be ran while influxdb is running ? |
|
No, this tool is for offline conversion. The idea is to switch new shards to TSI and then do old shard conversion offline if necessary. |

Overview
This adds an
inmem2tsicommand toinflux_inspectthat allows for the conversion of an in-memory index to aTSIindex. The index is written to a temporary location until complete and then moved to its permanent location. If any error occurs then it will fallback to the in-memory index.This is not intended as a hot shard conversion. New shards can be set to use TSI as their new index and old shards can be converted as needed. A server restart is required after a shard is converted.
