Schema changes are detected, need to cache previous log state in memory for a few seconds on ingestion nodes (inconsistency is ok as long as data type is the same because they will be compacted and deduplicated if same column name)

  • Track schema on ingest
  • If take not of schema changes
  • Cache current schema in memory
  • Have background process for refreshing known in-memory schema from log (set interval, 0 is off)
