Apache IoTDB vs BTrDB
Both stand on time-series databases. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Open source APILinuxMac+3
Apache IoTDB provides a range of ingestion paths, query features and deployment options for IoT time-series data. For Java applications where write performance matters, its documentation recommends the Java Native API rather than JDBC inserts.

Choose BTrDB if you need an open-source, self-hosted store for dense telemetry, with versioned streams and Python-based querying. Look elsewhere if SQL support is required or if your workflow depends on Arrow-based tabular methods without commercial access and an Arrow-enabled server.
