It's an EDB feature in the sense that Heikki is developing it as part of his employment with EDB, but it will be committed to community PostgreSQL. See the thread on interruptible sleeps. The problem right now is that there are some polling loops that act to throttle the maximum rate at which a node doing sync rep can make forward progress, independent of the capabilities of the hardware. Those need to be replaced with a system that doesn't inject unnecessary delays into the process, which is what Heikki is working on. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
