Subject: chunkd near-term enhancements
Date: Sun, 04 Jul 2010 02:26:43 -0400 [thread overview]
Message-ID: <4C3029A3.6010001@garzik.org> (raw)
Here are a few chunkd enhancements that are currently on my drawing
board, for the near term:
(CHO_xxx denotes new chunkd network protocol commands, as listed in
include/chunk_msg.h)
* CHO_SET_SERVERS:
chunkd shall maintain a per-connection buffer known as SERVER_LIST.
This chunkd command is issued by the client prior to using a
SERVER_LIST-related command (see below), to reset the contents of the
connection's SERVER_LIST buffer.
* CHO_RCP:
copy a single object to each remote server in SERVER_LIST
* CHO_PUT_THRU:
like PUT, but causes chunkd to further replicate the incoming object to
each remote server in SERVER_LIST
* CHO_APPEND:
append data onto an object.
* CHO_APPEND_THRU:
append data locally, and, replicate foreach remote server in SERVER_LIST
The authentication used in chunkd->chunkd connections is the logged-in
username/shared-secret combination.
