Apothecary is a suite of HBase related utilities from Explorys

Some highlights of Apothecary are:

1. An alternative implementation of an InputFormat to allow you to use HBase as a source for mapreduce jobs.
   • Reads directly from on disk storefiles
   • In our testing, > 3 times faster
   • Use responsibly, be aware of the operational constraints
2. A drop in in-memory replacement for HTable
   • Isolate your unit tests from your datastore without the pain
   • Implements HTableInterface
3. MapFile.Reader improvements
   • Allows for multithreaded index lookups
   • Isolate all of the Immutable Parameters from the disk operations
