HyperTable is a C++ BigTable clone with a Thrift API and production deployments at Baidu and Rediff Mail (100 million users) storing metadata and metrics. Benchmarks on a 16‑node cluster with 5 TB show HyperTable roughly 2x faster than HBase for random reads and writes and HBase suffers GC collapse at small value sizes. Features include a query cache, atomic counters with no random IO, regex filters using Google re, namespaces and 1 billion cells inserted in 45 minutes via secondary indexes.
