How does HBase manage concurrent data access?
HBase uses Multi-Version Concurrency Control (MVCC) to handle concurrent data access. When multiple clients access the same row of data simultaneously, HBase controls each write operation by assigning a separate timestamp to each cell. This ensures that each client can read or write the latest version of data without losing any information.
Furthermore, HBase also utilizes read-write locks to control concurrent access to data. During read operations, multiple clients can access the same row data simultaneously without conflicts. During write operations, only one client can obtain the write lock, ensuring data consistency and reliability.
In general, HBase ensures data consistency and reliability by using MVCC and read-write locks to handle concurrent data access.
