Local Parquet source

The root directory is set through the root-base-dir property, which supports scope parameter placeholders. The DLC ensures that only files within that source can be loaded.

Configuration properties

Properties for a Local Parquet Source are defined by name in the dlc.parquet.local.sources namespace, and are picked up as configurations for the DLC.

Key	Required	Type	Description
root-base-dir	Y	`String`	Root base directory. Can include Scope Parameters. Example `#{SCOPE_PARAM}`
topics-to-include		`Set<String>`	Topics to include. See source to topic matching.
topics-to-exclude		`Set<String>`	Topics to exclude. See source to topic matching.
accepts-topic-overrides		`Boolean`	Whether this source is allowed to accept Topic Overrides in the Load Request.

YAML example

dlc:
  parquet:
    local:
      sources:
        localParquetSource:
          root-base-dir: data
        datedSource:
          root-base-dir: data/#{AS_OF_DATE}
