The Aerospike Node.js Client v2.0 has been released with significant performance improvements due to the switch from blocking I/O to non-blocking I/O in the underlying Aerospike C/C++ client library. Benchmark tests showed that the new version achieved about 78,500 read & write operations per second, an increase of more than 29% over the performance of the v1.0.57 client. The non-blocking I/O also improved query and scan performance with significantly reduced memory consumption. These enhancements are expected to provide a better developer experience for users of Aerospike's Node.js Client.
