Execution and Commit of Transactions
During the execution of a transaction, PostgreSQL ensures that it operates on a consistent snapshot of the database. Once the transaction completes its operations, it can commit its changes to the database, creating new versions of the affected rows with updated transaction IDs.
Example:
-- Example of committing a transaction in PostgreSQL
BEGIN;
-- Perform operations
COMMIT;
Multiversion Concurrency Control (MVCC) in PostgreSQL
PostgreSQL is a powerful open-source relational database management system known for its robustness and reliability. One of its key features that sets it apart from other databases is Multiversion Concurrency Control (MVCC). MVCC allows multiple transactions to occur concurrently while ensuring data consistency and integrity.
In this article, We will learn about Getting Started with Multiversion Concurrency Control (MVCC) in PostgreSQL in detail.
