 |`druid.indexer.task.baseTaskDir`|Base temporary working directory for 
tasks.|`${druid.indexer.task.baseDir}/persistent/task`|
 |`druid.indexer.task.batchProcessingMode`| Batch ingestion tasks have three 
operating modes to control construction and tracking for intermediary segments: 
`OPEN_SEGMENTS`, `CLOSED_SEGMENTS`, and `CLOSED_SEGMENT_SINKS`. `OPEN_SEGMENTS` 
uses the streaming ingestion code path and performs a `mmap` on intermediary 
segments to build a timeline to make these segments available to realtime 
queries. Batch ingestion doesn't require intermediary segments, so the default 
mode, `CLOSED_SEGMENTS`, eliminates `mmap` of intermediary segments. 
`CLOSED_SEGMENTS` mode still tracks the entire set of segments in heap. The 
`CLOSED_SEGMENTS_SINKS` mode is the most aggressive configuration and should 
have the smallest memory footprint. It eliminates in-memory tracking and `mmap` 
of intermediary segments produced during segment creation. 
`CLOSED_SEGMENTS_SINKS` mode isn't as well tested as other modes so is 
currently considered experimental. You can use `OPEN_SEGMENTS` mode if problems 
occur with the 2 ne
 wer modes. |`CLOSED_SEGMENTS`|
