1. A method comprising:
receiving, by one or more processing devices of a search head leader of a cluster comprising a plurality of search heads, from a first search head of the cluster, a first journal entry relating to a first customization of a knowledge object, wherein the first search head performs a first reduce phase of a first map-reduce search computation of source data in accordance with the first customization, and wherein each search head of the cluster is configured to perform a reduce phase of a map-reduce search computation;
determining, by the one or more processing devices of the search head leader, that the first journal entry references a parent commit journal entry matching a latest commit journal entry in a journal maintained by the search head leader;
storing, by the one or more processing devices of the search head leader, the first journal entry in the journal; and
sending, by the one or more processing devices of the search head leader, the first journal entry to a second search head of the plurality of search heads of the cluster, wherein the second search head adds the first journal entry to a second journal maintained by the second search head.
