Frame of Reference and Roaring Bitmaps
Postings listsWhile it may surprise you if you are new to search engine internals, one of the most important building blocks of a search engine is the ability to efficiently compress and quickly decode sorted lists of integers. Why is this useful? As you may know, Elasticsearch shards, which are Lucene indices under the hood, split the data that they store into segments which are regularly merged
Roaring Bitmaps
A better compressed bitset Roaring bitmaps are compressed bitmaps. They can be hundreds of times faster. Grab one of our research papers Roaring Bitmaps on GitHub Widely used Roaring is found in Google Procella: YouTube’s SQL Engine, Apache Lucene and derivative systems such as Solr and Elasticsearch, Apache Druid, Apache Spark, Apache Hive, Apache Tez, Apache Zeppelin, Apache Doris, Apache Carbon
