Topic said that persistence of memory-grant-feedback and percentile testing is currently not available in Azure Managed Instance. My testing indicates that it is, and I assume that the text I deleted was a leftover.

Pull request overview

This PR updates the Memory Grant Feedback documentation to reflect that persistence (and related feedback persistence) is available in Azure SQL Managed Instance, removing the prior statement that it isn’t.

Changes:

  • Update the “Percentile and persistence mode memory grant feedback” section to include Azure SQL Managed Instance for persistence defaults.
  • Remove the bullet stating percentile/persistence isn’t available in Azure SQL Managed Instance.
  • (Unintended) Front matter change appears to break YAML formatting for f1_keywords.

- Percentile memory grant feedback is enabled by default in [!INCLUDE [ssSQL22](../../includes/sssql22-md.md)], but has no effect if Query Store isn't enabled or when Query Store isn't in a "read write" state.

- Persistence for memory grant, CE, and DOP feedback is on by default in [!INCLUDE [ssSQL22](../../includes/sssql22-md.md)], but has no effect when Query Store isn't enabled or when Query Store isn't in a "read write" state.
- Persistence for memory grant, CE, and DOP feedback is on by default in [!INCLUDE [ssSQL22](../../includes/sssql22-md.md)] and [!INCLUDE [ssazuremi-md](../../includes/ssazuremi-md.md)], but has no effect when Query Store isn't enabled or when Query Store isn't in a "read write" state.

- Percentile and persistence for memory grant feedback is available in [!INCLUDE [ssazure-sqldb](../../includes/ssazure-sqldb.md)], and enabled by default on all databases, both existing and new.

Yeah, I am not entirely fond of this topic, as pieces have been added as the new features have been coming in, so a fresh start would be welcome. I decided not to go there myself, but only correct the information about MI.
