Techniques are disclosed relating to caching techniques for processing a database change stream. A computer system may receive change records from a change stream that includes a plurality of records indicating changes to a database table. The change stream may include change records for multiple shards and be accessible by providing one or more position indicators for one or more of the multiple shards to request one or more change records and an updated position indicator. The system may store, for changes to a set of one or more shards, one or more cache entries that include respective groups of change records. The system may request a portion of the change stream by providing a received position indicator. The system may provide one or more cached change records from a cache entry that matches the provided position indicator.
