1. Introduction to the replicator database

A database where you PUT/POST documents to trigger replications and you DELETE to cancel ongoing replications. These documents have exactly the same content as the JSON objects we used to POST to /_replicate/ (fields "source", "target", "create_target", "continuous", "doc_ids", "filter", "query_params".

Replication documents can have a user defined "_id". Design documents (and _local documents) added to the replicator database are ignored.

The default name of this database is _replicator. The name can be changed in the .ini configuration, section [replicator], parameter db.

    var local_var = 'whatever'
    second_action(local_var)
