1. A computer-implemented method for managing update information associated with items of an electronic catalog, comprising:

  • under control of one or more computing devices;

    obtaining, from an archive data store, updates associated with an indexing key, wherein the updates comprise a change associated with an item of an electronic catalog, wherein at least a subset of the updates is purged from a live data store to the archive data store, and wherein the live data store is associated with a dynamic index that indexes the subset before the subset is purged;

    aggregating the updates into an object;

    indexing the updates in a static index of the archive data store by associating a pointer to the object with the indexing key in the static index;

    obtaining a request for update data associated with the electronic catalog, wherein the request for update data includes a query key that is matched to determine whether the update can be obtained from the static index or the dynamic index; and

    generating a response to the request based, at least in part, on a match to the indexing key on the static index, wherein the response includes the pointer to the object, wherein the pointer corresponds to the match to the indexing key.
