Replication/mirroring documents by query

(Ville Mattila) #1


I'd need to make a local almost real-time copy of a part of large indexes. Before implementing this logic in our application layer, I was wondering id there are already existing tools in Elasticsearch to do this? Or is there something I should consider otherwise?

The documents to copy is defined by a query (or filter). Documents that have been modified in remote should be updated to the local copy.possible deleted documents should be deleted too as well as new documents inserted. Conflicts are not possible: updates are always routed via the master.

The connectivity between the remote and local is unstable.

All your ideas and comments are welcome!
