Description

Hypothetical scenario:

• node comes up and needs to recover
• node starts buffering updates and replicating index
• node receives and buffers 1000 updates and dies before replication finishes
• node comes up, replays tlog
• peersync checks last 100 updates, they match, and node goes into "active" state (without having ever finished the index replication)
