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 Problems | compactor | LokiCompactorSchemaConfigurationStorageObservabilityIndex |
