instead of remove query cache of OQ_GRAPH, use dependant table functions from query cache (like partition engine)
—
points to check, from sql/ha_partition.cc

my_bool ha_partition::reg_query_cache_dependant_table(THD *thd,
                                char *engine_key, uint engine_key_len,
                                char *cache_key, uint cache_key_len,
                                uint8 type,
                                Query_cache *cache,
                                Query_cache_block_table **block_table,
                                handler *file,
                                uint *n)
uint ha_partition::count_query_cache_dependant_tables(uint8 *tables_type)
my_bool ha_partition::register_query_cache_dependant_tables(THD *thd,
                                      Query_cache *cache,
                                      Query_cache_block_table **block_table,
                                      uint *n)
