TiDB in a Nutshell - Power of Open-Source Distributed SQL Database - Mydbops
- 1. TiDB Architecture In Nutshell May 27th, 2023 Mydbops Webinar - 22 Kabilesh PR Co-Founder, Mydbops
- 2. Interested in Open Source technologies MySQL / TiDB Certified Professional Tech Speaker/Blogger AWS certified Database speciality AWS community builder / SME Co-Founder, Mydbops IT Solutions Kabilesh PR About Me
- 3. Mydbops Services Consulting Services Managed Services Focuses on MySQL, MongoDB, PostgreSQL Targeted Engagement 24 x 7 DBA Team
- 4. Agenda What is TiDB ? Architecture Production Readiness Sharding
- 5. What is TiDB ? • An Open Source distributed SQL database by PingCAP • Scalability in both ways horizontally and vertically • Supports both Transactional and Analytical workload in realtime • Compatible with MySQL protocol • Highly available and Fault Tolerance
- 6. MySQL scalability - Bottlenecks Monolithic - Single node Limitation Horizontal scaling - Sharding
- 7. Architecture TiDB cluster - SQL layer Tikv - Storage layer TiFlash - Analytical columnar storage Placement Driver(PD) - Metadata & TSO
- 8. Architecture
- 9. TiDB - SQL Interface • Stateless • Handles Client connections & authentication • Parsing & compiling • Coverting relational to KV pair (Tikv) • Executing SQL • Online DDL execution • Garbage collections • Cache table
- 10. TiKV - Transactional Storage • Stateful • Persistent storage with RocksDB • Distributed storage & transaction support • Strong Consistency • MVCC support • Inbuilt HA • Co-Processor (PP)
- 11. TiKV - Regions and Raft • Region - Represents a range of key-value data • 96 Mb in size • A region is replicated to multiple nodes forming Raft group • Regions are automatically balanced across TiKV nodes • Each region has a leader and followers • Leader handles RW ops • Followers replicate , server read & can be promoted as leader via election • PD Maintains the region info,scheduling,balacing
- 12. Services (LB) Stateful Sets Operator Maturity TiKV - Regions and Raft
- 13. Placement Driver - PD • Metadata management - Global view • Data placement and load balancing • TransactionID allocation • Global Timestamp (TSO) • Scheduling by collecting cluster info • PD consists of 3 node at-least
- 14. TiFlash - Analytical Store Columnar storage Replicated Async from Tikv Intelligent engine selection Optimised for aggregation, join & table scans MPP (Multiple Parallel Processing)
- 15. Architecture
- 16. Sharding Supports on the fly sharing & distribution Relational to Key-value transformation Distributed based on Global key Global_key = Primary_key + Table_id(generated) For Non-int primary key row_id is generated
- 17. Sharding - Relational to KV
- 19. Sharding - Region split & distribution
- 20. Production Readiness Definitely YES !! its ready to be deployed Know the current limitation of Tidb Test your usecase
