CLeveldb: Coalesced Leveldb for Small Data

초록

This paper proposes a coalesced key-value pairs generation technique for CLeveldb. The proposed method employs an additional buffer cache and Upper Meta file which increases write performance of CLeveldb by merging multiple small data into a larger chunk and provides consistency by logging each transaction in Upper Meta file. The preliminary experimental results show that, the proposed method improves the writing performance of small data by 6 times as compared with Leveldb as input key-value item size becomes smaller.
