case class RocksDBFileMappings(versionToRocksDBFiles: ConcurrentHashMap[Long, Seq[RocksDBImmutableFile]], localFilesToDfsFiles: ConcurrentHashMap[String, RocksDBImmutableFile]) extends Product with Serializable

Track file mappings in RocksDB across local and remote directories

versionToRocksDBFiles

Mapping of RocksDB files used across versions for maintenance

localFilesToDfsFiles

Mapping of the exact Dfs file used to create a local SST file The reason localFilesToDfsFiles is a separate map because versionToRocksDBFiles can contain multiple similar SST files to a particular local file (for example 1.sst can map to 1-UUID1.sst in v1 and 1-UUID2.sst in v2). We need to capture the exact file used to ensure Version ID compatibility across SST files and RocksDB manifest.
