Curator allows for many different operations to be performed to both indices and snapshots, including:

  • Add or remove indices from an alias
  • Shard routing allocation
  • Disabling Bloom filter caches (for versions of Elasticsearch < 1.4)
  • Close indices
  • Delete indices and snapshots
  • Open closed indices
  • Optimize indices
  • Change the number of replicas per shard for indices
  • Show indices and snapshots
  • Take a snapshot (backup) of indices.
