Gache notions

Basic idea

Like Memcached, plus...

Usability:
- True FLUSHALL
- Single process for multiple bins
Management
- Complete locking dump/restore
- Snapshots
Tag support
Pluggable storage
- Journaling
- Write-back/write-through replication
- Chained storage (fast → slow)

But probably slower overall, but more convenient.

Components

Server

Runner
- POSIX-style options, not native in Go
- Configuration loading for systemd (and others) integration
Protocol handling (FSMs)
- Application: Memcache protocol proper
- Presentation: ASCII / Binary
- Transport "connection":
- TCP with persistent connections
- TCP without persistent connections
- UDP
- raw socketpair (stdin/stdout)
- Event handling
Readline equivalence for ASCII presentation interactions
Storage
- Pluggable storage
- Journaling
- Storage engines
- Memory
- Memcached, for use as a debugging proxy in front of a standard instance
- Others ?
- Memory
  - Main memory allocation
  - Slab allocator
- Reporting
- Background expiration lurker
