The short version
- Each has a real cost: Elasticsearch eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements; TiDB not 100% MySQL-compatible, requiring verification before migration
- They diverge on capability: Elasticsearch covers Full-text Search, TiDB covers MySQL Compatible.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Elasticsearch
- Eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements
- No support for ACID transactions or rollbacks; updates delete and re-insert documents
- JVM-dependent architecture requires careful memory management and monitoring to prevent garbage collection issues at scale
TiDB
- Not 100% MySQL-compatible, requiring verification before migration

Answered from the vendors’ own pages
Elasticsearch: Is Elasticsearch free?
Yes, Elasticsearch can be deployed as free and open-source software for self-managed installations. Elastic Cloud managed service starts at $16.40 per month, with a free 14-day trial available.
SourceTiDB: 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.
SourceElasticsearch: Can I use Elasticsearch without Kibana?
Yes, Elasticsearch is a search engine independent of Kibana. Kibana is a visualization and analytics tool that works with Elasticsearch but is optional. You can use the Elasticsearch API directly for searching.
SourceTiDB: 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.
SourceElasticsearch: Does Elasticsearch support real-time indexing?
Elasticsearch indexes data with a refresh interval, typically 1 second. Data becomes searchable after the refresh cycle, making it near-real-time but not instantaneous. This can be configured but impacts performance.
SourceTiDB: 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.
SourceElasticsearch: What are Elasticsearch's scaling limitations?
Elasticsearch requires careful operational management at scale, including shard balancing, heap sizing, and monitoring. Large clusters can suffer from garbage collection issues and become expensive to operate.
SourceElasticsearch: Does Elasticsearch support transactions and rollbacks?
No, Elasticsearch does not support ACID transactions or rollbacks. Updates are expensive operations that delete and re-insert documents, making it unsuitable for transactional workloads.
