Arrow

When a table uri ends in .arrow or .arrows, ROAPI will try to load it as Arrow IPC file or stream if no format option is specified:

tables:
  - name: "mytable"
    uri: "http://mytable.arrow" # or .arrows

You can partition an Arrow dataset into multiple partitions and load all of them into a single table by directory path:

tables:
  - name: "mytable"
    uri: "./table_dir"
    option:
      format: "arrow" # or arrows
