Apache Druid stores data partitioned by time chunk in immutable files called segments. Data management operations involving replacing, or deleting, these segments include:
- Updates to existing data.
- Deletion of existing data.
- Schema changes for new and existing data.
- Compaction and automatic compaction, which reindex existing data to optimize storage footprint and performance.
