Microsoft made the following changes in their documentation (see screenshot above) to accurately reflect the memory limits on lower editions of SQL Server.

Key Points

  • The limits for In-Memory OLTP data is per database.
  • The limits for Columnstore segment cache is per SQL Server instance across all the databases in the instance.

Example Scenario

A Standard Edition of SQL Server has buffer pool memory limited to 128GB, so the data and index pages cached in buffer pool is limited by 128GB. Starting with SQL Server 2016 SP1, you can have an additional 32GB of memory for Columnstore segment cache per instance and an additional 32GB of memory quota for In-Memory OLTP per database. In addition, there can be memory consumed by other memory consumers in SQL Server which will be limited by “max server memory” or total memory on the server if max server memory is uncapped.
