### Description
While doing some experiments with big5 workload on Opensearch, I noticed
significant ByteArrayDataInput allocations during aggregation query execution.
I noticed the allocations were coming from
`Lucene90DocValuesProducer$TermsDict.decompressBlock`. I used below query for
this experiment:
```
POST big5/_search?request_cache=false
{ "size": 0,"aggs": {"agent": {"cardinality": {"field": "event.id"}}}}
```
This is the snapshot from allocation flamegraph:
