In an earlier post I noted that Berkeley DB Java Edition cleaner performance had improved significantly in release 5.x. From an Oracle NoSQL Database point of view, this is important because Berkeley DB Java Edition is the core storage engine for Oracle NoSQL Database.
Berkeley DB Java Edition 5.x has significant performance improvements. One user noted that they are seeing a 20x improvement in cleaner performance.
Here's an Oracle NoSQL Database customer success story for Passoker, an online betting house.
There are a lot of great points made in the Solutions section, but as a developer the one I like the most is this one:
We ran a set of YCSB performance tests on Oracle NoSQL Database using SSD cards and Intel Xeon
E5-2690 CPUs with the goal of achieving 1M mixed ops/sec on a 95% read / 5% update workload. We used the standard YCSB parameters: 13 byte keys and 1KB data size (1,102 bytes after serialization). The maximum database size was 2 billion records, or approximately 2 TB of data.
