TiDB Roadmap

This roadmap provides a look into the proposed future. This will be continually updated as we release long-term stable (LTS) versions. The purpose is to provide visibility into what is coming, so that you can more closely follow the progress, learn about the key milestones on the way, and give feedback as the development work goes on.

In the course of development, this roadmap is subject to change based on user needs and feedback. As expected, as the columns move right, the items under them are less committed. If you have a feature request or want to prioritize a feature, please file an issue onGitHub.

Rolling roadmap highlights

Category	End of CY23 LTS release	Mid of CY24 LTS release	Future releases
Scalability and Performance Enhance horsepower	GA of Partitioned Raft KV storage engine PB-scale clusters, increased write velocity, faster scaling operations, and improved compaction stability Augmented replica read Reduced cross-AZ data transfer costs in TiKV	Performance optimization framework for all applicable background tasks, like DDL, TTL, and cluster analysis This distributes the workload of these operations throughout the cluster, leading to accelerated performance and reduced resource utilization on individual nodes. This framework already applies to the`ADD INDEX`operation GA of disaggregated storage and compute architecture and S3 shared storage in TiFlash Enable more cost-effective and elastic HTAP	Unlimited transaction size
Reliability and Availability Enhance dependability	Resource control for background tasks Control over how background tasks, such as imports, DDL, TTL, auto-analyze, and compactions, can affect foreground traffic	Multi-tenancy Resource isolation on top of resource control	Enhanced TiDB memory management
SQL Enhance functionality and compatibility	MySQL 8.0 compatibility Unified SQL interface for import, Backup & Restore, and PITR	Cascades framework for optimizer 改进的框架,用于查询优化和麦e the optimizer more extensible and future-proof	Federated query Full text search & GIS support User-defined functions
Database Operations and Observability Enhance DB manageability and its ecosystem	Distributed TiCDC single table replication Dramatically improve TiDB-TiDB replication throughput Automatic pause/resume DDL during upgrade Ensure a smooth upgrade experience TiCDC native integrations with big data systems Such as Snowflake and Iceburg	Multiple upstreams for TiCDC Support N:1 TiDB to TiCDC	AI-indexing Heterogeneous database migration support Re-invented AI-SQL performance advisor
Security Enhance data safety and privacy	Key management via Azure Key Vault Static encryption managed by Azure Key Vault Column-level access control Grant and restrict access to specific columns Database-level encryption At-rest encryption configured at database level	IAM authentication for AWS TiDB as AWS third-party ARN for AWS IAM access Unified TLS CA/Key rotation policy Unified certificate management mechanism for all TiDB components	Label-based access control Access permissions granted by configured labels 增强客户端加密 Enhanced data masking Enhanced data lifecycle management

These are non-exhaustive plans and are subject to change. Features might differ per service subscriptions.
