Database is very complex ● Lots of RPC work ● Keep high performance ● Tons of data ● Huge amount of OLTP queries ● Very complex OLAP queries ● External Consistency ● SQL is much more complex than KV all queries in one session ● Introduce a cache in goyacc ● Resource pool OLTP & OLAP 8am 2pm 6pm 2am ETL Database OLTP OLAP Data Warehouse Is the data out-of-date? TiSpark Thanks! Contact me:

Scalability as the first class feature ● SQL is necessary ● Compatible with MySQL, in most cases ● OLTP + OLAP = HTAP (Hybrid Transactional/Analytical Processing) ● 24/7 availability, even in case of datacenter
