Summary:
Created a tool that runs multiple threads that concurrently read and write to levelDB.
All writes to the DB are stored in an in-memory hashtable and verified at the end of the
test. All writes for a given key are serialzied.
Test Plan:
- Verified by writing only a few keys and logging all writes and verifying that values read and written are correct.
- Verified correctness of value generator.
- Ran with various parameters of number of keys, locks, and threads.
