[ANN] Slowpoke (database engine)

[vadim kulibaba]

Hi Everyone,

I finished simple and effective key/value store with nice api:
https://github.com/recoilme/slowpoke

The performance was not a target of this database but it performs well and not so slow as i expected. It just stores values in files and keys with value addresses in memory, with persistence. No LSM-tree, no BTree, no mmap, just standard library (hash table+slice in goroutine).

Let me know what you think!

How it is compacted?
Values will be updated and deleted, storage file will grow. How garbage will be collected?

Keys storage not grow, they are overriding on an update, values override too if size of old value is sufficient

If no - it will grow. I have plans to add compaction on backup in future. 

Right now backup may be implemented in three command (sets(gets(keys())))
