static class |
GlobalOrdinalsStringTermsAggregator.LowCardinality
Variant of
GlobalOrdinalsStringTermsAggregator that resolves global ordinals post segment collection
instead of on the fly for each match.This is beneficial for low cardinality fields, because it can reduce
the amount of look-ups significantly. |
static class |
GlobalOrdinalsStringTermsAggregator.WithHash
Variant of
GlobalOrdinalsStringTermsAggregator that rebases hashes in order to make them dense. |

BucketCollector
collect
in class BucketCollector
owningBucketOrdinal
- The ordinal of the bucket this aggregator belongs to, assuming this aggregator is not a top level aggregator.
Typically, aggregators with #bucketAggregationMode
set to Aggregator.BucketAggregationMode.MULTI_BUCKETS
will heavily depend on this ordinal. Other aggregators may or may not use it and can see this ordinal as just
an extra information for the aggregation context. For top level aggregators, the ordinal will always be
equal to 0.IOException
