# DescribeGlobalTableSettings
<a name="API_DescribeGlobalTableSettings"></a>

Describes Region-specific settings for a global table.

**Important**  
This documentation is for version 2017.11.29 (Legacy) of global tables, which should be avoided for new global tables. Customers should use [Global Tables version 2019.11.21 (Current)](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GlobalTables.html) when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017.11.29 (Legacy).  
To determine which version you're using, see [Determining the global table version you are using](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/globaltables.DetermineVersion.html). To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see [Upgrading global tables](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/V2globaltables_upgrade.html).
