    Ongoing Tasks - General Info

    • Ongoing tasks are work tasks defined for the database.
    • Once defined, these tasks are ongoing, meaning that they will do the defined work for any data change in the database.
    • Each task has a responsible node from the Database Group nodes, this node will actually perform the defined task work.

    • The available ongoing tasks are:

      • External Replication
        • Create a live copy of one database in another RavenDB database
        • This replication is initiated by a node in the source database group
      • Pull Replication
        • Create a live copy of one database in another RavenDB database
        • This replication is initiated by a node in the destination database group
      • RavenDB ETL
        • Write all database documents, or just part of it, to another RavenDB database
        • Data can be filtered and modified with transformation scripts
      • SQL ETL
        • Write the database data to a relational database
        • Data can be mutated with transformation scripts
      • Backup
        • Schedule a backup or a snapshot of the database at a specified point in time
      • Subscription
        • Sending batches of documents that match a pre-defined query for processing on a client
        • Data can be mutated with transformation scripts

      • Active - Task is active and will do its job when there is a change to the database
      • Not-Active - Task is defined but has been disabled
      • Not on Node - The node in the currently viewed tab is not responsible for performing the task
      • Reconnect - Destination is unavailable, the task is active and trying to reconnect

    3. The node that is currently responsible for doing the task

      • If not specified by the user, the cluster decides which node will actually be responsible for the task
      • If a node is down, the cluster will reassign the work to another node for the duration
