Bushbaby Automated Bamboo Yields

Sync for Bamboo stores using the Bushbaby protocol

Connection tuning

The per-connection idle timeout is governed by three settings, all read from Application config (config :baby, ...) at connection startup:

• :outrate — milliseconds between outbox ticks. Default: a random prime near 75 (jittered so connections don't tick in lockstep).
• :max_spins — idle budget, in outbox intervals, once the initial replication sync has completed. Default: a random prime near 1200.
• :bootstrap_spins — idle budget while the initial sync is still in progress, giving the peer time to compute its WANT list before being dropped. Default: a random prime near 3000.

The idle counter resets on any send or receive, so the budgets measure consecutive silence rather than wall-clock time on a busy link. A connection that exceeds its budget is dropped and re-established on the next cryout.

To estimate wall-clock time, multiply the budget by :outrate — e.g. a default max_spins of ~1193 at a default outrate of ~80ms is roughly 95 seconds, and a default bootstrap_spins of ~2969 is roughly 4 minutes.
