goleveldb VS squirrel

Looks like a job for GoLevelDB.

goleveldb - Implementation of the LevelDB key/value database in Go.

I wanted to get deeper insights into both indexeddb and leveldb, so decided to write an indexeddb wrapper around goleveldb.

https://github.com/syndtr/goleveldb for heavy-duty local data storage.

We're using go-leveldb for a reasonably high-load case here at my $dayjob.

I would used some embedded kv store like go-leveldb or bolt. Key is BigEnding timestamp + optional tail to allow duplicate timestamps.

I'm using the leveldb https://github.com/syndtr/goleveldb for the moment because I'm developing the architecture. Mh, leveldb support the only the inmem db? :/

I built https://github.com/anacrolix/squirrel for just this purpose. However you might find that batch inserting empty files might only be 10x faster or so than creating empty files directly on the filesystem if we are to believe the 10k/s the OP achieved.

I'm looking for an embedded database/KV-store that supports a write-heavy workload of large blocks of bytes and some kind of eviction policy. I'm currently using sqlite3 with a bunch of triggers and the blob API, but it's not really suitable for write-heavy workloads. I've currently exposed the interface somewhat in https://github.com/anacrolix/squirrel, the primary use case is from https://github.com/anacrolix/torrent. My recent research suggests an LSM-based KV-store like rocksdb or leveldb, but those don't have great interfaces in Go, and don't seem to support an eviction policy as far as I can tell (which is surprising given they would be very well suited to it). There are some alternatives like buntdb, but those all look designed for smaller/string values.
