Sound familiar?
- ▸ TiKV region hotspots — one region is taking 10× the write traffic of the others, PD scatter rules aren't fixing it, and you're hitting raft-store timeouts during peaks.
- ▸ TiFlash replica lag — analytical queries that used to hit columnar replicas are now reading from TiKV (slow), because TiFlash replication is behind and you can't tell which tables are affected.
- ▸ MySQL → TiDB cutover stuck — DM (Data Migration) tool is dropping rows, the binlog filter isn't handling DDL changes, and the dual-write phase keeps producing checksum mismatches.

Where do you migrate TiDB to (or from)?
TiDB is most often a destination, not an origin. The six paths below cover both directions — TiDB as the migration target from MySQL/PostgreSQL, and the alternatives we recommend when TiDB isn't the right fit. We pick honestly based on workload.
MySQL → TiDB
Driver: Horizontal scale + HTAP
Most common path TO TiDB. MySQL-compatible wire protocol, distributed SQL, TiFlash columnar replicas on the same engine. Cutover via TiDB DM with binlog replay. We solve the DDL-during-sync and dual-write checksum gotchas.
PostgreSQL → TiDB
Driver: Wire-protocol re-target
Less common — TiDB’s MySQL wire protocol means application changes. Best when PG cluster outgrew Citus / sharding and you want a managed distributed SQL with HTAP. We handle the type-mapping and procedural code conversion.
TiDB → CockroachDB
Driver: PostgreSQL wire + active-active
Migrating OFF TiDB toward CockroachDB usually means you wanted PostgreSQL semantics or stronger multi-region active-active. Different SQL dialects and wire protocols (MySQL-compatible TiDB vs PostgreSQL-compatible CockroachDB) mean cutover via dual-write or a CDC pipeline (TiCDC).
TiDB → YugabyteDB
Driver: PostgreSQL compatibility
Move when your application code is PG-native and the MySQL wire protocol is adding friction. YugabyteDB’s YSQL is PG-compatible — we re-model the schema and re-write the cutover playbook.
TiDB → Aurora MySQL
Driver: Drop the distributed-SQL tax
When you no longer need horizontal write scale — Aurora MySQL is simpler to operate and cheaper for sub-10TB workloads. Cutover via mysqldump + binlog replay; we handle the storage-class and IOPS sizing.
TiDB Self-Managed → TiDB Cloud
Driver: Managed offload
Stay on TiDB but offload PD / TiKV / TiFlash operations to PingCAP’s managed service. Best fit when in-house TiDB ops capacity is the constraint. We model the TCO and run the dataset migration.

How JusDB TiDB Consulting compares to alternative models.
Standard managed cloud providers and generic IT consultancies lack deep TiKV Raft consensus tuning, TiFlash MPP workload isolation, and continuous DBRE reliability ownership. Here is how our TiDB specialists compare across core architectural dimensions:
| Evaluation Vector | JusDB DBRE | In-House DBA | Legacy Agency | Developer Generalist |
|---|---|---|---|---|
| Distributed HTAP Architecture (TiKV vs TiFlash Isolation) | Architects strict workload isolation using tidb_isolation_read_engines to decouple OLTP and OLAP execution. Configures dedicated TiFlash columnar MPP engines with automated replication lag tracking, preventing analytical scans from saturating TiKV row storage or spiking transaction p99 latencies. | Runs analytical queries directly against TiKV row storage without configuring TiFlash replicas, causing CPU saturation, Raft thread starvation, and unpredictable transaction latency spikes. | Treats TiDB as a standalone monolithic MySQL instance; relies on unindexed secondary queries and external batch ETL cron jobs that duplicate data and stall transactional performance. | Enables TiFlash replicas globally without configuring query engine hints, join type routing, or memory quotas, leading to runaway MPP memory consumption and out-of-memory worker crashes. |
| Monotonic Write Hotspot Mitigation (AUTO_RANDOM & Sharding) | Eliminates sequential write bottlenecks using AUTO_RANDOM primary keys, SHARD_ROW_ID_BITS, and PRE_SPLIT_REGIONS. Distributes high-throughput batch inserts evenly across all TiKV stores and Raft leader groups for near-linear write scaling. | Relies on standard AUTO_INCREMENT primary keys on high-velocity tables, concentrating 100% of write traffic onto a single TiKV region leader and creating severe disk I/O bottlenecks. | Attempts application-level sharding or external queuing workarounds, introducing distributed transaction overhead without addressing underlying TiKV monotonic key ordering mechanics. | Applies random UUID primary keys without factoring in clustered index fragmentation, degrading range scan performance and ballooning RocksDB LSM-tree write amplification. |
| Placement Driver (PD) Sizing & Region Merge Scheduling | Calibrates PD scheduling rules, automated empty-region merging, and dynamic leader balancing across availability zones. Optimizes TSO (Timestamp Oracle) lease allocation to maintain sub-millisecond transaction start latencies under petabyte-scale loads. | Leaves PD scheduling policies at default values, allowing millions of empty or micro-regions to accumulate from drop/truncate operations and exhausting PD control-plane memory. | Lacks understanding of PD Raft consensus and region heartbeats, manually restarting PD nodes during scheduling delays and triggering cluster-wide leader election storms. | Aggressively forces region splits without adjusting merge thresholds or scatter limits, saturating network bandwidth with continuous peer migrations. |
| Multi-Raft Consensus & Network Latency Tuning | Tunes Multi-Raft heartbeats, election timeouts, raft-store sync-log frequency, and gRPC message streaming over 10GbE/100GbE networks. Isolates Raft commit I/O with dedicated WAL drives to keep commit latency low and predictable. | Co-locates Raft WAL logs and RocksDB data on shared, un-tuned EBS volumes, triggering frequent Raft election drops and write-stall cascades during disk I/O bursts. | Treats consensus replication delays as standard network blips and ignores disk sync latency metrics, leading to silent transaction timeouts and leader transfers. | Deploys cross-region TiKV replicas across high-latency WAN links without follower-read configurations or leaseholder locality rules, stalling two-phase commit rounds. |
| SQL Plan Management (SPM) & Query Plan Stability | Enforces deterministic execution plan baselines via SQL Plan Management (CREATE BINDING), continuous ANALYZE TABLE scheduling, and extended statistics. Prevents optimizer plan regressions following cluster upgrades or data skew shifts. | Relies solely on default cost-based optimizer decisions without plan baselines; experiences sudden index-skip regressions and full-table scans when stats become stale. | Suggests manual query rewrites or application-level caching whenever query execution degrades, unable to inspect or pin TiDB distributed execution plans. | Scatters FORCE INDEX hints across codebase repositories, breaking query plans when schemas evolve or distributed coprocessor pushdowns change. |
| TiDB Dedicated Cloud vs Self-Managed TCO Sizing | Conducts data-driven TCO modeling comparing TiDB Dedicated Cloud against self-managed Bare-Metal or Kubernetes topologies. Sizes compute, local NVMe storage classes, cross-AZ traffic, and licensing to reduce total operational spend. | Over-provisions self-managed virtual machines with generic cloud SSDs, incurring runaway cloud infrastructure bills while failing to meet distributed I/O requirements. | Pushes managed cloud migrations without calculating data transfer costs, backup retention fees, or dedicated instance markups, resulting in unforeseen budget spikes. | Attempts ad-hoc cloud sizing using single-node MySQL pricing formulas, severely underestimating the multi-component footprint of TiDB, TiKV, PD, and TiFlash. |
Critical TiDB Production Failure Modes We Eliminate
Operating distributed TiDB clusters at scale introduces complex consensus, storage hotspot, and replication lag failure vectors. Our DBREs proactively diagnose and eliminate these production breakdown modes:
Monotonic Auto-Increment Primary Key Hotspotting
Using standard AUTO_INCREMENT primary keys concentrates sequential write throughput onto a single TiKV region and its Raft leader. Disk I/O saturates on one storage node while the remainder of the cluster sits idle, causing cascading write timeouts.
JusDB re-engineers schemas to utilize AUTO_RANDOM primary keys or SHARD_ROW_ID_BITS with PRE_SPLIT_REGIONS, scattering insert payloads uniformly across all TiKV stores and maximizing parallel Raft commit throughput.
Placement Driver (PD) Control-Plane Congestion
High-frequency table drop/truncate cycles and small-region proliferation generate millions of empty or micro-regions. Placement Driver memory saturates, heartbeats get delayed, and TSO (Timestamp Oracle) allocation latency spikes, stalling all distributed transactions.
JusDB tunes PD region-merge schedulers, lowers merge thresholds, increases max-merge-region-size, and implements aggressive empty-region consolidation, reducing PD memory pressure and keeping TSO latency under 1ms.
TiFlash Columnar Replication Lag Stalling Analytical Queries
Massive transactional write bursts cause Raft Learner synchronization lag between TiKV and TiFlash. Analytical queries fall back to scanning TiKV row storage or stall waiting for TiFlash delta-tree compaction, degrading OLTP and OLAP performance simultaneously.
JusDB isolates analytical read engines via tidb_isolation_read_engines, tunes TiFlash Learner thread pools, provisions dedicated NVMe disks for TiFlash delta-cache storage, and sets SLA-driven replication lag circuit breakers.
Our TiDB DBREs execute non-blocking telemetry inspections to identify region write hotspots, monitor key distribution, and audit Placement Driver cluster balance without disrupting active workloads:
Queries internal information_schema tables to detect high-traffic TiKV regions, unbalanced write flow, and key access skew across the cluster.
SELECT * FROM information_schema.tidb_hot_regions ORDER BY flow_bytes DESC LIMIT 10;
Inspects PD member consensus health, leader election status, TiKV store capacity, and region distribution across storage nodes.
