# Global tables version 2017.11.29 (Legacy)
<a name="globaltables.V1"></a>

**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)](GlobalTables.md) when possible, as it provides greater flexibility, higher efficiency and consumes less write capacity than 2017.11.29 (Legacy).   
To determine which version you are using, see [Determining the version of a global table](V2globaltables_versions.md#globaltables.DetermineVersion). To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see [DynamoDB global tables versions](V2globaltables_versions.md).
