TLDR It's not our choice, but it's meaningful. Because this 5GB is single data segment and literally what you will have in Elastic/etc when you have overall TBs of data. See https://www.elastic.co/docs/deploy-manage/production-guidance/optimize-performance/size-shards https://www.elastic.co/docs/deploy-manage/production-guidanc... (single shard is one Lucene index that contains multiple data segments)
