Joyce Wells reports in Database Trends and Applications, “Oracle is introducing a major new release of its NoSQL database – version of 4.0. First unveiled in 2011, the Oracle NoSQL Database is a key-value database that evolved from the company’s acquisition of BerkeleyDB Java Edition, a mature, high-performance embeddable database. While Oracle is well known for its relational database technology, fundamentally, Oracle focuses on data management in general, and views NoSQL as one of the key products in the data management space from Oracle, said Ashok Joshi, senior director of NoSQL, Berkeley Database, and Database Mobile Server at Oracle.”
Wells goes on, “Oracle releases quarterly updates to the NoSQL database. Among the 5 key enhancements Oracle is making in NoSQL 4.0, said Joshi, are: (1) Support for ‘time-to-live’: This is relevant for the IoT and sensor data capture space where typically users want to store 3–6 months’ worth of data, but data that is older is not relevant. This feature enables the option of deciding that data can be automatically aged out of the system or moved offline after a certain set period of time, said Joshi. (2) Predicate pushdown: As part of the larger Oracle data framework, Oracle NoSQL works well with the Oracle Database. It allows a query to be run from Oracle Database against data that is stored in the NoSQL Database, essentially connecting the two repositories together.”
