Real-World Scenarios: When to Choose Which

The question that matters: “In what situation will I regret choosing A over B after 3 months?”

Scenario: JSONB Indexing for Flexible Schema

PostgreSQL

JSONB Indexing for Flexible Schema Without NoSQL Migration

PostgreSQL's JSONB with GIN indexes stores semi-structured data in relational tables and queries nested keys at under 5ms, avoiding a full NoSQL migration for use cases that need occasional schema flexibility.

TiDB

Scale OLTP to 1 Billion Rows Without Application Rewrites

TiDB's horizontal scaling adds storage and compute nodes without schema changes or connection string updates, extending a MySQL-compatible application to multi-terabyte scale transparently.

PostgreSQL Unique Strength

Table Partitioning Cuts Time-Series Query Time by 90%

Declarative partitioning splits large time-series tables into monthly partitions, cutting query scan time by 90% for date-range queries that previously scanned billions of rows.

→ Choose PostgreSQL if this scenario applies to you. TiDB doesn't offer a comparable solution.

PostgreSQL Unique Strength

Logical Replication for Zero-Downtime Migration

Logical replication syncs a live production database to a new instance in real time, enabling a migration cutover measured in seconds rather than the hours a pg_dump/restore requires.

→ Choose PostgreSQL if this scenario applies to you. TiDB doesn't offer a comparable solution.

TiDB Unique Strength

Run Analytics on Live Transactional Data via TiFlash

TiDB's TiFlash columnar replica allows analytical SQL queries to run against real-time transactional data without ETL delay, replacing nightly data warehouse loads for operational reporting.

→ Choose TiDB if this scenario applies to you. PostgreSQL doesn't offer a comparable solution.

TiDB Unique Strength

Online DDL on Live Tables Without Locking

TiDB performs column additions, index builds, and table restructuring on live tables without locking, avoiding the scheduled maintenance windows that interrupt MySQL deployments during schema changes.

→ Choose TiDB if this scenario applies to you. PostgreSQL doesn't offer a comparable solution.
