Class ReindexingIndexSpecRule

java.lang.Object

org.apache.druid.server.compaction.AbstractReindexingRule

org.apache.druid.server.compaction.ReindexingIndexSpecRule

All Implemented Interfaces:

ReindexingRule

public class ReindexingIndexSpecRule
extends AbstractReindexingRule

A ReindexingRule that specifies an IndexSpec for reindexing tasks to configure.

This rule controls compression and encoding settings independently from partitioning. For example, applying different bitmap or metric compression to older data.

This is a non-additive rule. Multiple index spec rules cannot be applied to the same interval.

Example inline usage:

 {
   "id": "compressed-90d",
   "olderThan": "P90D",
   "indexSpec": {
     "bitmap": { "type": "roaring" },
     "metricCompression": "lz4"
   },
   "description": "Use roaring bitmaps and lz4 for data older than 90 days"
 }
