Summary:
Completed the implementation for the Redis API for Lists.
The Redis API uses rocksdb as a backend to persistently
store maps from key->list. It supports basic operations
for appending, inserting, pushing, popping, and accessing
a list, given its key.
Test Plan:
- Compile with: make redis_test
- Test with: ./redis_test
- Run all unit tests (for all rocksdb) with: make all check
- To use an interactive REDIS client use: ./redis_test -m
- To clean the database before use: ./redis_test -m -d
