1. A method comprising:
accessing, by one or more processing devices corresponding to a first search head of a cluster comprising a plurality of search heads of a data aggregation and analysis system, a first list of knowledge object customizations corresponding to the first search head;
propagating a digest of the first list of knowledge object customizations corresponding to the first search head to a second search head of the cluster;
receiving an indication of a first divergence point determined between the first list of knowledge object customizations and a second list of knowledge object customizations corresponding to the second search head based on a comparison of the digest with the second list of knowledge object customizations, the first divergence point corresponding to a first position in the first list of knowledge object customizations; and
based on the divergence point, sending a first set of knowledge object customizations from the first list of knowledge object customizations to the second search head.
