The short version

  • Only TiDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Firebolt compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop; TiDB not 100% MySQL-compatible, requiring verification before migration
  • They diverge on capability: Firebolt covers Sub-second Queries, TiDB covers MySQL Compatible.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Firebolt

  • Compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop
  • Storage pass-through charged at $0.0264/GB monthly on compressed data; uncompressed storage could exceed this
  • Azure deployment currently in Preview status; production recommendations unclear
  • Vector indexes limited to float arrays; other data types require alternative indexing strategies
  • Free tier credits ($200) limited; no perpetual free tier for production use

TiDB

  • Not 100% MySQL-compatible, requiring verification before migration

Answered from the vendors’ own pages

TiDB: Is TiDB MySQL-compatible?

Yes, TiDB speaks the MySQL protocol, so existing MySQL clients, ORMs, and drivers work without modification. However, TiDB is not 100% MySQL-compatible.

Source
TiDB: How does TiDB scale?

TiDB provides automatic horizontal scaling with compute and storage scaling independently. It splits compute (TiDB servers) from storage (TiKV) to allow adding nodes without data replication.

TiDB: Does TiDB support analytics workloads?

Yes, TiDB is an HTAP database with TiFlash columnar engine providing analytics capabilities alongside transactional processing on the same data without separate pipelines.
