This was mostly just a side project for fun to figure out how background saving might be emulated in golang. It does not handle race conditions currently and is not usable for any real purpose.

Goal

Redis like caching^Wcashing service in golang

Example

Start the server. (fyi listen's by default only on localhost)

$ go run ./cmd/main.go

In another shell connect to it on localhost:6379 with nc.

$ nc localhost 6379
set mykey somevalue34344 

get mykey
somevalue34344
del mykey
(integer) 1
get mykey
(nil)
set mykey 8

incr mykey
9
get mykey
9

Ideas

TODO

Development

SAVE

Because redis uses fork(2) to save a copy of in memory data with a background process and given the fact golang can't fork(2) in this way I ended up implementing the in memory hash tree as copy on write with a snapshot function. SAVE or BGSAVE isn't fully implemented right now but this CoW/Snapshot behaivor should serve the same function as fork(2) upstream.
