How does HBase ensure data integrity during write operations?
- Compression
- Consistency Checks
- Replication
- Write-Ahead Log (WAL)
HBase ensures data integrity during write operations through the Write-Ahead Log (WAL). Before making changes to the data store, HBase writes the modifications to the WAL. In the event of a failure, the system can recover the changes from the WAL, ensuring data consistency and durability.
