Gathering Information On Memory-Optimized Objects

Ned Otter has a diagnostic script for learning about how your servers are using memory-optimized objects:

Instance level evaluates the following:

  • which databases are memory-optimized
  • if running Enterprise, if there are any resource groups defined, and which databases are bound to them
  • version/edition of SQL server
  • ‘max memory’ setting
  • whether or not instance-level collection of execution statistics has been enabled for all natively compiled stored procedures
  • memory clerks for the buffer pool and In-Memory OLTP
  • the value of the committed_target_kb column from sys.dm_os_sys_info
  • display any event notifications (because they conflict with deploying In-Memory OLTP

Database level evaluates the following:

For each memory-optimized database:

  • database files, including container names, size, and location

  • memory-optimized tables

  • indexes on all memory-optimized tables

  • count of indexes per memory-optimized table

  • natively compiled stored procedures

  • whether or not the collection of execution statistics is enabled for any natively compiled procedures

  • count of natively compiled procedures

  • if using the temporal feature for memory-optimized tables, the amount of memory consumed by hidden temporal internal tables

  • memory structures for LOB columns (off-row)

  • average chain length for HASH indexes

Ned provides the script on his blog, so click through to get that.  This looks great if you’re trying to build up some basic information on how developers in your environment use memory-optimized objects.

Memory-Optimized Table Types

Rob Farley hates spelling “optimized” the best way: Let me start by saying that if you really want to get the most out of this feature, you will dive deep into questions like durability and natively-compiled stored procedures, which can really make your database fly if the conditions are right. Arguably, any process you’re doing […]

Testing Memory-Optimized tempdb

Erin Stellato wants to see how big a benefit using In-Memory OLTP for tempdb metadata objects really is: I have SQL Server 2019 CTP 3.2 installed on my virtual machine, which has 8GB of memory (max server memory set to 6 GB) and 4 vCPUs. I created four (4) tempdb data files, each sized to […]
