Hi, In class Lucene80DocValuesConsumer#writeValues(FieldInfo field, DocValuesProducer valuesProducer), all numericDocValues will be visited to calculate gcd, in the meantime, we can check if all values were sorted. if so, maybe we could use DirectMonotonicWriter to store them. DirectMonotonicWriter can get impressive compression.
In addition, when i use Elasticsearch to store numeric field types, in Lucene level, the data always at least stored by NumericDocValues/SortedNumericDocValues. So when indexing some sorted values like ID, TIMESTAMP, maybe the upon optimization is applicable. Could I have some suggestions? --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
