 Feature | Description
 --------+-------------------------
+[Read Committed isolation]({% link {{ page.version.version }}/read-committed.md %}) | Achieve predictable query performance at high workload concurrencies, but without guaranteed transaction serializability.
 [Follower Reads]({% link {{ page.version.version }}/follower-reads.md %}) | Reduce read latency in multi-region deployments by using the closest replica at the expense of reading slightly historical data.
 [Multi-Region Capabilities]({% link {{ page.version.version }}/multiregion-overview.md %}) | Row-level control over where your data is stored to help you reduce read and write latency and meet regulatory requirements.
 [PL/pgSQL]({% link {{ page.version.version }}/plpgsql.md %}) | Use a procedural language in [user-defined functions]({% link {{ page.version.version }}/user-defined-functions.md %}) and [stored procedures]({% link {{ page.version.version }}/stored-procedures.md %}) to improve performance and enable more complex queries.

 `READ COMMITTED` is one of two [transaction isolation levels](https://wikipedia.org/wiki/Isolation_(database_systems)) supported on CockroachDB. By default, CockroachDB uses the [`SERIALIZABLE`]({% link {{ page.version.version }}/demo-serializable.md %}) isolation level, which is the strongest [ANSI transaction isolation level](https://wikipedia.org/wiki/Isolation_(database_systems)#Isolation_levels).
