// Describes Region-specific settings for a global table.
//
// 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)]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]. To update existing global tables
// from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see [Upgrading global tables].
//
