Connection Management: Brian
|
||
|
|
v1: foolscap, no relay, live == connected-to-queen, broadcast updates, full mesh
|
||
|
|
v2: live != connected-to-queen, connect on demand
|
||
|
|
v3: relay?
|
||
|
|
|
||
|
|
Encoding: Zooko
|
||
|
|
v1: fake it (replication), no merkle trees
|
||
|
|
v2: mnet codec
|
||
|
|
v3: merkle tree to verify each share
|
||
|
|
v4: merkle tree to verify each segment
|
||
|
|
|
||
|
|
Peer selection:
|
||
|
|
v1: permuted peer list, consistent hash
|
||
|
|
|
||
|
|
filetable maintenance:
|
||
|
|
v1: steal webfront code, encodingsdb, queen.set_filetable_uri
|
||
|
|
|
||
|
|
checker/repairer:
|
||
|
|
v1: none
|
||
|
|
v2: centralized checker, repair agent
|
||
|
|
v3: nodes also check their own files
|
||
|
|
|
||
|
|
storage: RobK
|
||
|
|
v1: no deletion, one directory per verifierid, one owner per share,
|
||
|
|
leases never expire
|
||
|
|
v2: leases expire, delete expired data on demand, multiple owners per share
|
||
|
|
|
||
|
|
|
||
|
|
back pocket ideas:
|
||
|
|
when nodes are unable to reach storage servers, make a note of it, inform
|
||
|
|
queen eventually. queen then puts server under observation or otherwise
|
||
|
|
looks for differences between their self-reported availability and the
|
||
|
|
experiences of others
|
||
|
|
|
||
|
|
big questions:
|
||
|
|
convergence?
