I notice when ingesting csvs, where I want to allow for null values, I see:
exceptions: [could not convert value [] to double,could not convert value [] to double,could not convert value [] to double,could not convert value [] to double,could not convert value [] to double,could not convert value [] to double,]
at org.apache.druid.segment.incremental.IncrementalIndex.getCombinedParseException(IncrementalIndex.java:757) ~[druid-processing-0.15.0-incubating.jar:0.15.0-incubating]
at org.apache.druid.segment.incremental.IncrementalIndex.add(IncrementalIndex.java:611) ~[druid-processing-0.15.0-incubating.jar:0.15.0-incubating]
at org.apache.druid.segment.realtime.plumber.Sink.add(Sink.java:180) ~[druid-server-0.15.0-incubating.jar:0.15.0-incubating]
I'd like to set maxParseExceptions to 0, but then these will halt the ingestion. How can we ingest null values for a double dimension without creating parse exceptions?
