WonderDB

Key Features

* Single Node NoSql database - NoSql database with support for relational, document (xml, json) and name/value pair. It will also support custom datatypes and functions. * WonderDB Cache - It can be configured as a disk backed java application cache configured to use hash index or BTree+ index based on the query needs. This can be used when cache footprint is growing bigger than physical memory. Note that, It extends to memory outside of JVM heap thorough use of direct byte buffers so you don’t have to increase JVM heap size after integrating with this cache. * Resource Journaling / Redo Log Manager - This product provides transactional commit and rollback semantic to any serializable resource. It stores serialized resource to look ahead redo log files only on commits. And also periodically (configurable) serializes the resource to its destination in multiple threads for better performance. * Single Node transactional NoSql database - NoSql database with support for relational, document (xml, json) and name/value pair. It will also support custom datatypes and functions. * Implementation of select classes in java.util.concurrent package - This product provides disk backed implementation of WonderDB’s hash index and BTree+ index. They will be available as implementation of some of the Map and list related concurrent util classes. This implementation also uses external memory outside of JVM heap. If your application has a need to store large lists or large object sorting, then this may be very useful feature for you. We have seen 40K TPS for Btree+ and 60K+ TPS for hash index accesses.
