Related to #35303 Slice of `storage.PrimaryKey` will have extra interface cost for each element, which may cause notable memory usage when delta row count number is large. This PR replaces PrimaryKey slice with PrimaryKeys interface saving the extra interface cost. --------- Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
