1. A method comprising:

  • receiving data at a particular indexer belonging to a first user-specified grouping of indexers, the first user-specified grouping of indexers associated with a particular geographic location;

    storing, by the particular indexer, at least one grouped subset of the data in a data store accessible by the particular indexer;

    selecting, by a master node, a set of peer indexers based on both of (i) a user-specified indexer replication factor indicating a number of separate indexers at which the at least one grouped subset of the data is to be stored, and (ii) a separate user-specified site replication factor indicating a number of sites at which the at least one grouped subset of the data is to be stored, each site corresponding to a separate geographic location that is different from the first geographic location;

    generating, by the master node, replication instructions identifying the selected set of peer indexers;

    receiving, by the particular indexer, the data replication instructions identifying the selected peer indexers; and

    sending, by the particular indexer, the at least one grouped subset of the data to the peer indexers based on the data replication instructions.
