SQL Index and Data Source Cache is an optimized plug-in package designed to accelerate Spark SQL* performance by using index and cache technology at the Spark SQL data source layer. Indexing can improve Spark interactive query performance by as much as an order of magnitude, and caching delivers additional Spark SQL query performance benefits. We support both DRAM and Intel® Optane™ Persistent Memory as cache media.
