What it guarantees

An instance keeps its live state in memory while the write-ahead history is the durable copy. A dormant instance comes back from its latest closed state plus the log records after it.

  • Hold state durably without an attached volume to provision
  • Batch history uploads so object requests stay affordable
  • Bring an instance back on demand after it goes dormant or moves
