Cache updating

Technology is described for performing cache data invalidations. The method may include identifying cache update information at a first cache. The cache update information may identify a cache entry (e.g., a trending cache entry). A second cache may be selected to receive the cache update information from the first cache. The cache update information identifying the cache entry may be sent from the first cache to the second cache. For example, the second cache may be populated by adding the trending cache entry into the second cache.
