Docker Analytics Interface

Docker analytics interface executes Kestrel analytics via docker.

An analytics using this interface should follow the rules:

• The analytics is built into a docker container reachable by the Python docker package.

• The name of the container should start with kestrel-analytics-.

• The container will be launched with a mounted volumn /data/ for exchanging input/output.

• The input Kestrel variables (all records) are put in /data/input/ as 0.parquet.gz, 1.parquet.gz, …, in the same order as they are passed to the APPLY command.

• The output (updated variable data) should be yielded by the analytics to /data/output/ as 0.parquet.gz, 1.parquet.gz, …, in the same order of the input variables. If a variable is unchanged, the output parquet file of it can be omitted.

• If a display object is yielded, the analytics should write it into /data/display/.
