Default Isolation Levels across database systems
20 September,2021 by Rambler
The isolation levels define which database objects are locked and how long that lock is held for. They are one of the critical concepts related to concurrency in transactions.There is a fair amount of variety across DBMS types.
DB2 LUW - CS Isolation with CUR_COMMIT enabled
SQL Server - Read Committed
MySQL - Repeatable Read
MariaDB - Repeatable Read
Oracle - Read Committed
MongoDB - Read uncommitted
PostgreSQL - Read Committed
