CoreBunch/Instaticv4.20.2Aug 9, 2026by swilly22

AI Summary

Introduces significant replication improvements by defaulting to effect-based replication for indices and constraints. It also enhances query stability by aborting paused queries and implementing robust divergence detection.

Key Highlights

  • Replication now uses effects by default, including indices and constraints.
  • Queries are now aborted when the system is paused.
  • Replica divergence is detected, triggering a full sync automatically.
  • Queries are queued during stub loading to prevent failures.

New Features

  • Effect-based replication for indices and constraints.
  • Query abortion mechanism for paused states.
  • Replica divergence detection and synchronization.
