Title: Inside Out: TiDB’s Table Partition and Data Definition Language (DDL)

Time: November 7th, 6 PM Pacific Daylight Time. Doors will open at 5:30 PM.


In this talk, we will discuss two important aspects of TiDB: Table Partition and Data Definition Language (DDL).

Mattias will first talk about Table Partitioning in TiDB. He will introduce table partitioning in TiDB and MySQL compatibility. He will also go through the most common use cases, the specifics of TiDB and how the distributed SQL system and HTAP affects the use cases for table partitioning. 

You can also discuss with Mattias about planned features and user requests.

Cong will then give a talk about the overview of Data Definition Language (DDL) execution of TiDB, including how the online schema change works in a HTAP distributed system: the challenging parts and the solutions to archive them. Cong will also discuss the compatibility of TiDB with MySQL in DDL: the features that have been supported, not supported and extended. Also, he will give a brief introduction to the roadmap of DDL in TiDB.
