I’m using druid.coordinator.merge.on which merges segments to arbitrary long segments, time wise.
When updating these segments http://druid.io/docs/latest/ingestion/update-existing-data.html I’m not quite sure how to setup hadoop indexing job.
IngestionSpec.IoConfig.IngestionUpdateSpec takes :
intervals - does it serve simply as time restriction, so that I can put single interval that spans all segments that I want to reindex ?
segments - if not specified, get resolved using /druid/coordinator/v1/metadata/datasources/segments
IngestionSpec.DataSchema.ArbitraryGranularitySpec takes :
- intervals - what about this one, does it also serve as a time restriction ?
As you can see, I’m not quite sure what to put into Intervals to reindex all segments that I have in data-source.
