rpc-rproxy

A fast JSON RPC reverse proxy with on the fly parsing and unix domain socket support.
Supposed to be used with Ethereum Nodes but will work with any JSON RPC protocol.

Under Development - This should not be used by anyone in production yet

TODO

• Reverse Proxy
  • Unix Domain Socket
  • HTTP
• Session Handling
  • One to one mode
  • Pooled mode
  • Single upstream
  • Graceful disconnects
  • Reconnects
    • Pub/Sub Replay
  • Stream Parsing (Lexing / Seperating Objects)
    • Buffered
    • Instant/Blocking
  • SQLite Logs

Honestly I am already quite happy with the performance we got here. Every iteration is "parsing" about 32k bytes of json. There may be a SMID version of this in the future.

The benchmark test of this is highly WIP and may return totaly bogus numbers.
