We are pleased to announce the production release of OMNIDEX Version 5. This incorporates major changes below which greatly simplify installation and provide a further leap in query performance.
Simpler and Higher-Performing Indexing
Omnidex 5.0 combines all indexing features into one index type, simplifying the installation of indexes and greatly speeding index builds. Earlier versions of Omnidex used separate index types for searching and aggregating. Criteria was generally optimized with MDK indexes, and aggregations were generally optimized with ASK indexes. This frequently required administrators to index some columns twice, once with each index type, thus increasing build time and system resources. Indexes suitable for aggregations and ordering were also built individually, requiring many scans of the underlying data. Omnidex 5.0 allows all indexes to be processed in one batch. In heavily indexed scenarios, this can result in a 500% improvement in build performance and a 50% reduction in disk space.
Support for XML Environment Files
Omnidex 5.0 introduces XML files as the new storage approach for Omnidex Environment Files. Historically, Omnidex Environment Files were created by compiling a source file into an Environment File. Omnidex 5.0 now records all information in a highly versatile and portable XML file. Compiled Environment Files are still supported for backward compatibility; however, new features will be developed using the new XML format.
