If a consensual system loses so many of its replicas that it cannot form a quorum, that system is theoretically in a non-recoverable state, because permanent protocols cannot access at least one of the missing replicas. If no quorum is retained, it is possible that a decision has been made, which has only been seen by the missing aftershocks. Administrators can force a change of membership in the group and add new replicants that are removed from the existing replicator to continue, but the possibility of data loss still remains – a situation that should be avoided to the full extent possible. If an applicant obtains the approval of the majority of recipients, he can accept the proposal by sending a message of commitment with value. Distributed consensus algorithms are low-level and primitive: they simply allow a series of nodes to agree once on a value. They are not neatly ordered on real design tasks. What makes distributed consensus useful is adding superior system components such as data memory, configuration storage, queues, blocking and Leader voting services to provide the system`s practical functionality that does not address distributed consensus algorithms. The use of higher components reduces complexity for system designers. In addition, the underlying distributed consensus algorithms can, if necessary, be modified in response to changes in the environment in which the system is run or changes to non-functional requirements.
Indeed, many problems related to distributed systems turn out to be different versions of the distributed consensus, including election masters, group membership, all types of distributed locking and leasing, reliablely distributed queues and couriers, as well as maintaining any kind of critical common state that must be considered consistently in a process group. All of these problems should only be solved by distributed consensus algorithms, which have been formally correct and whose implementations have been extensively tested. In practice, ad hoc ways to solve these types of problems (such as heartbeats and gossip) will always have reliability problems. There are a number of corrective measures to address the agent`s main problem, and many of them include clarifying expectations and tracking results. The client is usually the only party who can or wants to solve the problem. Who is causing the problem and who is affected? A simple brainstorming session is a great way to determine this. The problem has been studied in synchronous and asynchronous communications. Logically, the principle cannot constantly monitor the agent`s actions. The risk that the officer will decide to take responsibility, make a bad decision or otherwise act in a manner contrary to the best of the client can be defined as agency fees. Additional agency fees may arise when problems arise as a result of an agent`s actions.
Agency fees are considered part of the transaction costs. After defining the problem, ask if everyone understands the terminology used.
