We've added documentation to the Akka.NET website that explains how to use this tool here: https://getakka.net/articles/clustering/cluster-sharding.html#cleaning-up-akkapersistence-shard-state And the tool itself has documentation here: https://github.com/petabridge/Akka.Cluster.Sharding.RepairTool | COMMITS | LOC+ | LOC- | AUTHOR | | --- | --- | --- | --- | | 16 | 1254 | 160 | Gregorius Soedharmo | | 7 | 104 | 83 | Aaron Stannard | | 5 | 8 | 8 | dependabot[bot] | | 4 | 876 | 302 | Ismael Hamed | | 2 | 3942 | 716 | zbynek001 | | 2 | 17 | 3 | Andreas Dirnberger | | 1 | 187 | 2 | andyfurnival | | 1 | 110 | 5 | Igor Fedchenko |
