Description |
Wide-column store based on Apache Hadoop and on concepts of BigTable |
In-memory key-value store,originally intended for caching | One of the most popular document stores | In-memory database with configurable options performance vs. persistency | A widely usedenterprise search enginebased onApache Lucene | @H_301_6@ Developer |

In any design decisions performance has priority over features or memory requirements. | Architecture: Lives in web stack,ships by default with Jetty. Connectors,JDBC,multiple languages,true morphological CJK,binary document filters (Tika),Entity Extraction (UIMA) | @H_301_6@ Typical application scenarios |
Mostly used for caching | Applications that can hold all data in memory,and that have high performance requirements. |
