之前收集了一些存儲產品，最近又重新整理了一下，對他們進行了簡單的分類。每個對存儲的分類可能不僅相同，我的分類完全按照自己的喜好來分，如和您的分類不同，僅供參考。只是做了蒐集和分類，少量產品加了寫介紹，希望以後有時間，加更多更詳細的介紹。

1.存儲引擎

1.1 Hash Table

1.1.1 dbm (database manager)

https://en.wikipedia.org/wiki/Dbm

The dbm library stores arbitrary data by use of a single key (a primary key) in fixed-size buckets and uses hashing techniques to enable fast retrieval of the data by key.

1.2.2 LMDB (Lightning Memory-Mapped Database)

LMDB is a Btree-based database management library modeled loosely on the BerkeleyDB API, but much simplified. The entire database is exposed in a memory map, and all data fetches return data directly from the mapped memory, so no malloc’s or memcpy’s occur during data fetches.
