The following environment variables control the generic batch streaming infrastructure behavior:
The interval (in milliseconds) for which a batch stream will wait before retrying when reading the batch process table.
The interval (in milliseconds) for which a batch stream will wait before retrying when reading the chunk key table.
The interval (in milliseconds) for which the main batch process (chunker) will wait before trying to scan for unprocessed chunks, once the value in the chunk key table has exceeded the number of chunks.
