We are constantly reviewing the functionality of our native multi-model solution to ensure it competes, and in many cases outperforms single-model alternatives. This provides numerous advantages to the user including optimized binary storage format, optional caching, reduced replication catch-up time, an exclusive collection access option, and enhanced WAL sync control.Ĭlaudius Weinberger, CEO of ArangoDB, said: “Improved usability and enhanced application performance are at the heart of every release we deliver. RocksDB is now the default Storage Engine: previous versions of ArangoDB used MMfiles as the default storage engine.Based on community feedback, 3.4 includes integrated streaming cursors which provide first results as they become available on the server. Streaming Cursors: at times the overall query performance is not a major priority, but rather how fast a user can obtain first results.To increase the reliability and predictability of the ArangoDB cluster, internal protocols and request handling have been significantly overhauled to improve cluster-wide query execution, an example being Distributed Collect. Cluster Management: enhancements include faster cluster startup, synchronization, and query execution.It is now much easier to profile your queries and get insights into how much time was spent where.
Query Profiler: to provide developers with more insight into complex queries, it is now possible to execute the query with special instrumentation code enabled resulting in a printed query plan with detailed execution statistics.Other notable enhancements in ArangoDB 3.4 include: Additionally, users can directly visualize results in OpenStreetMap which is integrated into the Query Editor of ArangoDBs WebUI. To this end, 3.4 also includes a Google S2 Geometry Library integration which complements ArangoDB’s RocksDB storage engine.
In 3.4 there has been a distinct engineering focus on increasing query and filtering functionality and optimizing performance. The support encompasses all geo primitives, including multi-polygons or multi-line strings.
Users can now perform relevance-based matching, phrase and prefix matching, search with complex Boolean expressions, query time relevance tuning and combine complex traversals, geo-queries, and other access patterns with information retrieval techniques.ĪrangoDB 3.4 includes full support for GeoJSON, an open standard format designed for representing simple geographical features, along with their non-spatial attributes. In search queries expressed with AQL, you can rank the results using multiple scorers (TFIDF and BM25) even combined. Within the view definition, one can specify entire collections or individual fields that should be covered by an inverted index using one or several general text analyzers. Search uses a special kind of materialized view to enable full-text search on multiple collections at once. If used in conjunction with graph database capabilities, search results could be used, for example, to enhance fraud protection, individualize recommendations or simplify precision medicine. ArangoSearch can be combined with all three data models in ArangoDB. The former is responsible for managing the index, querying and scoring, whereas the latter provides search capabilities for the end user in a convenient way.
Providing a rich set of information retrieval capabilities, ArangoSearch consists of two components - a search engine and an integration layer.
Major new enhancements in ArangoDB 3.4 include ArangoSearch, a feature which transforms ArangoDB, when combined with traversals or joins in AQL, from a data retrieval to an information retrieval solution and full GeoJSON Support enabled by a Google S2 Geo Index library integration.ĪrangoSearch, the result of four years of research and development, combines Boolean and generalized ranking retrieval models (e.g. ArangoDB announced the GA release of ArangoDB 3.4 - a transactional database solution which enables developers to efficiently interact with multiple data models by using just one technology and one query language.
