The record

Product: BTrDB is a time-partitioned, version-annotated, clustered time-series database for high-density univariate data.
Client library: The documentation provides Python access to BTrDB through the btrdb package.
Install: The maker recommends installing btrdb-python with pip and also documents installation with Anaconda.
Nanosecond timestamps: BTrDB’s example client uses nanosecond timestamps to query time-series values.
Aggregates: StatPoint queries can return min, max, mean, count, and standard deviation, with query time proportional to the number of results.
Versioning: Changes to a stream create a new version, allowing queries to be pinned to a specific version.
Stream collections: Streams have unique UUIDs and can be grouped into collections with tags and annotations for metadata.
Data formats: StreamSets can be filtered and converted to formats including pandas DataFrames and CSV files.
Commercial feature limit: Arrow-based tabular data methods are documented as available to commercial customers using Arrow-enabled servers.
Integrations: The Python documentation includes examples using Dash and Plotly to plot data queried from BTrDB.
Parallel processing: The client documents a serializer for passing BTrDB connections, streams, and StreamSets to Ray workers.
Security: The documentation describes TLS access on port 4411 and API-key authentication, which requires the TLS port.
Self-hosting and audience: The project describes BTrDB as deployable software and says Smartgrid.store targets very large city- or country-scale aggregation from smart-grid devices, while noting BTrDB can support other use cases.
Support: The documentation invites users to submit pull requests or open GitHub issues for additions or corrections.
