Tests
DataFilePathFactory.java
API and Format
Documentation
with data-file.external-paths config and data-file.external-paths.strategy configured as entropy-inject, It will use a hash of the file name to create multi-level directory structures, so that the request sent to object storage will be distributed, preventing beting throttled.
the path will be something like '${data_external_path}/0001/1110/0101/1111/bucket-1/data-xxx.parquet'
