Stratio’s Cassandra Lucene Index, derived from Stratio Cassandra, is an open sourced plugin for Apache Cassandra that extends its index functionality to provide near real time search such as ElasticSearch or Solr, including full text search capabilities and free multivariable, geospatial and bitemporal search. It is achieved through an Apache Lucene based implementation of Cassandra secondary indexes, where each node of the cluster indexes its own data. Stratio’s Cassandra indexes are one of the core modules on which Stratio’s BigData platform is based.
Andres de la Peña discusses the recently added geospatial search features in Stratio's Cassandra Lucene index using some Nephila Capital use cases. These new features include indexing complex polygons, nearest neighbour search, and the application of chained geometrical transformations such as bounding box, convex hull, centroid, union, intersection, exclusion and distance buffer.
