            // Run our reducer using the current query result and the mutation result.
            const nextQueryResult = tryFunctionOrLogError(() =>
              updater(currentQueryResult, {

      this.cache.performTransaction(c => {
        cacheWrites.forEach(write => c.write(write));
      });

      // If the mutation has some writes associated with it then we need to
      // apply those writes to the store by running this reducer again with a
      // write action.
      const update = mutation.update;
      if (update) {
        this.cache.performTransaction(c => {
          tryFunctionOrLogError(() => update(c, mutation.result));
        });
