Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
CockroachDB's geo-partitioning pins rows to specific cloud regions by key prefix, ensuring GDPR-regulated customer data never leaves EU nodes without sacrificing SQL query capability.
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.
CockroachDB's multi-zone deployment survives the loss of an entire availability zone automatically, with zero data loss and sub-30-second recovery versus minutes of manual failover for traditional primary/replica setups.
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.
CockroachDB's online schema changes apply column additions and index builds while the database serves traffic, avoiding the maintenance windows that single-node SQL databases require for schema changes.
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.
