-- The below scipt enables the use of In-Memory OLTP in the current database,
|
|
-- provided it is supported in the edition / pricing tier of the database.
|
|
-- It does the following:
|
|
-- 1. Validate that In-Memory OLTP is supported.
|
|
-- 2. In SQL Server, it will add a MEMORY_OPTIMIZED_DATA filegroup to the database
|
|
-- and create a container within the filegroup in the default data folder.
|
|
-- 3. Change the database compatibility level to 130 (needed for parallel queries
|
|
-- and auto-update of statistics).
|
|
-- 4. Enables the database option MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT to avoid the
|
|
-- need to use the WITH (SNAPSHOT) hint for ad hoc queries accessing memory-optimized
|
|
-- tables.
