Come have a look under the covers at new data structures that enable geospatial and multi-dimensional indexing and search at massive scale in Apache Lucene and Elasticsearch. This talk will cover not only the indexing structures considered and ultimately implemented in the Apache Lucene Open Source Project but the exceptional performance improvements and centimeter spatial accuracy obtained in the 7.6 and 8.0 release. As a bonus, this talk will cover new and upcoming Spatial Analysis Aggregations and Processing available in the Elastic Stack.
This talk will cover the algorithms and data structures written and committed to the following:
Apache Lucene (specifically the release of BKD based geo indexing https://issues.apache.org/jira/browse/LUCENE-8396)
Elasticsearch (https://github.com/elastic/elasticsearch/pull/36855)
