接口 ConsistencyProtocol<T extends Config,P extends RequestProcessor>

所有超级接口:

CommandOperations

所有已知子接口:

APProtocol<C,P>, CPProtocol<C,P>

public interface ConsistencyProtocol<T extends Config,P extends RequestProcessor>
extends CommandOperations

Has nothing to do with the specific implementation of the consistency protocol Initialization sequence： init(Config).

• Config : Relevant configuration information required by the consistency protocol, for example, the Raft protocol needs to set the election timeout time, the location where the Log is stored, and the snapshot task execution interval
• protocolMetaData() : Returns metadata information of the consistency protocol, such as leader, term, and other metadata information in the Raft protocol

方法详细资料

init

void init(T config)

Consistency protocol initialization: perform initialization operations based on the incoming. Config 一致性协议初始化，根据Config 实现类

参数:

config - Config

addRequestProcessors

void addRequestProcessors(java.util.Collection<P> processors)

Add a request handler.

参数:

processors - RequestProcessor

protocolMetaData

ProtocolMetaData protocolMetaData()

Copy of metadata information for this consensus protocol. 该一致性协议的元数据信息

返回:

metaData ProtocolMetaData

getData

Response getData(ReadRequest request)
          throws java.lang.Exception

Obtain data according to the request.

参数:

request - request

返回:

data Response

抛出:

java.lang.Exception - Exception

aGetData

java.util.concurrent.CompletableFuture<Response> aGetData(ReadRequest request)

Get data asynchronously.

参数:

request - request

返回:

data CompletableFuture

write

Response write(WriteRequest request)
        throws java.lang.Exception

Data operation, returning submission results synchronously. 同步数据提交，在 Datum 中已携带相应的数据操作信息

参数:

request - WriteRequest

返回:

submit operation result Response

抛出:

java.lang.Exception - Exception

writeAsync

java.util.concurrent.CompletableFuture<Response> writeAsync(WriteRequest request)

Data submission operation, returning submission results asynchronously. 异步数据提交，在 Datum中已携带相应的数据操作信息，返回一个Future，自行操作，提交发生的异常会在CompleteFuture中

参数:

request - WriteRequest

返回:

CompletableFuture submit result

抛出:

java.lang.Exception - when submit throw Exception

memberChange

void memberChange(java.util.Set<java.lang.String> addresses)

New member list . 新的成员节点列表，一致性协议自行处理相应的成员节点是加入还是离开

参数:

addresses - [ip:port, ip:port, ...]

shutdown

void shutdown()

Consistency agreement service shut down . 一致性协议服务关闭
