Ancient days of TiDB:
1,Inspired by Google Spanner,we made TiDB
2,In the 1.0.0 GA version,TiDB is
a,A freely scalable(computing,storage)database
b,Compatible with MySQL syntax and protocol
c,Transparent Data Spliting Policy-Range Spliting
d,Strongly consistent,distributed transaction support
Datahub Capability
1,TiDB is ideal for Datahub scenarios
2,Protocol-compatible,easy synchronization of MySQL production libraries
3,Transparent and accessible cross-segmentation queries.
4,Data landing in real time.
5,Massive storage allows multiple data sources to converge
6,Standby -Datahub Analysis 2-in-1
One year later
1,TP Scenario
a,CUSTOMER:There are still some problems though…Smells good!
2,AP Scenario
a,Client 1:Complex statements are so slow!
b,Clients:Always OOM!
c,Clients 3:Can’t integrate with a big data platform!
