Answer / Vipin Sonkar
In HBase, Write Ahead Logging (WAL) is a mechanism that ensures durability and crash recovery by recording all write operations in a log file. When a client sends a write request to HBase, the data is written to the WAL first before being persisted on disk. In case of a failure or crash, HBase can recover the lost data from the WAL, ensuring consistency and reliability.
