Xapiand is a Modern Highly Available Distributed RESTful Search and Storage Engine built for the cloud and with Data Locality. It features:
Liberal Open Source license:
- MIT license (Note Xapian engine itself is GNU GPL).
- You can find the source code for Xapiand at GitHub:
HTTP RESTful API:
- Document oriented.
- No need for upfront schema definition.
Search Engine:
- Built on top of Xapian{:target="_blank"} indexes.
Storage Engine:
- Each index also offers storage of files: à la Facebook's Haystack 1.
Support for query Aggregations.
Multi Tenant with Multi Types:
- Support for more than one index.
- Support for different types, one per index.
- Index level configuration:
- Schema.
Efficient and Scalable architecture:
- (Near) Real Time Search.
- Event driven asynchronous architecture using libev{:target="_blank"}.
- Written in modern C++.
Geo-spatial support:
- Uses The Hierarchical Triangular Mesh for indexing.
- Accepts multiple Coordinate Reference Systems, including WGS84.
- Implements EWKT.
High Availability:
- Automatic node operation rerouting.
- Replicas exists to maximize high availability and data locality.
- Read and Search operations performed on any of the replicas.
- Reliable, asynchronous replication for long term persistence.
Multi-Partitioning and Distribution Strategies:
- Social-Based Partitioning and Replication (SPAR 2).
- Random Consistent Partitioning and Replication.
