Animated, hands-on views of how Laredo moves data. Each runs in your browser — play, pause, and poke at it.

• The Laredo pipeline
  Postgres slot → engine demux → targets, with ACK held back by a slow target.
• Replication fan-out
  One server, many clients: snapshot bootstrap then a live journal stream + heartbeats.
• Snapshot writer: base + diff
  Base snapshot, periodic diffs, and threshold-driven re-bases into new epochs.
• Cross-instance failover
  GoAway → resume-by-LSN on another instance → drop the old one. No full re-sync.
• Ordering, ACK & backpressure
  In-order delivery, ACK = min(target positions), drop_disconnect vs slow_down.
