This document describes the latest and historical specifications of TDSQL-C for MySQL.
Note:
The current specification list may contain some deactivated specifications. Available specifications are listed on the purchase page.
In a TDSQL-C for MySQL cluster, read-write instances are by default exclusively compatible with the TXSQL engine, whereas read-only instances may opt between the TXSQL and LibraDB engines. The specifications for read-write and read-only instances under the TXSQL engine are identical, while the specifications for read-only instances under the LibraDB engine are distinct and separate.
If you need a higher specification to meet your storage needs, submit a ticket for assistance.
