Loki Compactor Schema Table MismatchLoki compactor encounters schema configuration mismatches when it finds index tables in object storage that don't correspond to any configured schema period in the Loki configuration. This causes the compactor to skip compaction for those tables, leading to storage inefficiency and potential query performance degradation. The issue typically occurs after schema migrations, configuration changes, or when legacy data exists with different table naming conventions.Observability ProblemscompactorLokiCompactorSchemaConfigurationStorageObservabilityIndex
