No video of the event yet, sorry!
TBase is an open source massively parallel processing (MPP) database server with an architecture designed for distributed transaction workloads. It is backed by experienced Tencent distributed database team. TBase is based on PostgreSQL 10.0 and supports similar SQL Standards, features and configuration options as PostgreSQl.
TBase adopt data sharding, GTM global timestamp technique and MVCC based on snapshot for both linear scalability and global consistent distributed transaction support. A new framework is implemented to make data redistribution and replication between data nodes more efficient, which largely improves distributed joins and aggregate function performance in parallel query execution.
Now TBase is widely used in Tencent and other enterprises, involving insurance, banking and other fields.
