hi, all: There are two ObjectStore::Transaction in ReplicatedBackend::submit_transaction, one is op_t and the other one is local_t. Is that something critilal logic we should consider? If we could reuse variable op_t it would be great. Because it is expensive to calling local_t.append(*op_t). There are similar logic in ReplicatedBackend::sub_op_modify_impl. -- Regards, xinze -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
