Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Databricks Delta Lake adds full ACID guarantees to Parquet files on S3 or ADLS, enabling concurrent reads and writes that corrupt data in plain Parquet pipelines without managing separate lock services.
Databricks integrates MLflow natively, auto-logging parameters, metrics, and model artifacts for every training run, reducing experiment comparison from hours of manual log parsing to a 30-second dashboard review.
Databricks Structured Streaming processes Kafka events with exactly-once semantics and checkpointed state, supporting stateful aggregations across time windows without losing events on job restart.
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.
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.
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.
