In one embodiment, as shown in Fig. 2, being configured between providing a kind of distributed type assemblies node based on operation log
Synchronous method, in this way be applied to Fig. 1 in cluster in host node for be illustrated, comprising the following steps:
S202 receives the configuring request that client is initiated.
Specifically, host node in cluster receives the configuring request that client is initiated, wherein cluster includes host node and more
It is a to can also be used as host node use from node, while from node, that is to say, that the node in cluster is either host node
It can be from node, but cannot occur simultaneously as host node or simultaneously as from the state of node.
Wherein, it when configuring request indicates that client needs to be updated configuration, needs to carry out configuration update to cluster sending
Request, updated including data and configuration associated with the data update etc., can be specifically divided into data and update request and configuration
Update request.
S204, respond are updated processing.
Specifically, after the host node in cluster receives the configuring request that client is initiated, the configuring request is responded, and execute
Update processing operation corresponding with configuring request.Wherein, host node is one in numerous nodes in cluster.
Wherein, the structure of configuration is typically all Key=Value form, and Key represents configuration name, and Value represents the configuration
Value.Comparison between configuration is divided into following three kinds:
1) have in the configuration received, and the Key that the configuration being locally stored is no, Key=Value is added from node pair
In the configuration answered.
2) Key having in the configuration for not having in the configuration received, and being locally stored, by this Key from being locally stored
It is deleted in configuration.
3) have in the configuration received, the Key also having in the configuration being locally stored, but Value is different, by this
Value value in the configuration of ground storage is updated to the value of Value in the new configuration received.
In the present embodiment, when the data that host node receives client initiation update request, host node will be read
Data update status be compared with the data of itself, when the data read are newly when the data of itself, by itself
Data are updated to read data.
When host node, which receives configuration, updates request, read due to the configuration more news that data update and generate,
And be compared the configuration with the configuration of itself, when what is read configures newly when the configuration of itself, by the configuration of itself
It is updated to read configuration.
S206 after update is disposed, generates more new logo.
Specifically, after host node updates the data of itself and configuration, more new logo is generated.Wherein, mark is updated
Knowledge is for judging whether node updates the mark finished.It specifically can be simple " Y " mark and " N " mark, " Y " mark
Knowing indicates that the node updates finish, and is updated after the case where finishing indicates the node respond herein, to data and
Configuration is updated processing operation, completes configuration and updates, can also be the data for indicating the node and configuration be it is newest,
The case where being updated again is not needed." N " mark indicates that the node does not update, and more news can be expressed as out herein
Existing loss of data etc. updates failure and leads to not complete to update.
More new logo can also be the operation note sequence number for recording configuring request, that is, update the flowing water of operation
Number.Specifically, each configuring request has the time of request and the difference of content, and the serial number for updating operation is updated for recording
The time of operation will record this time and update the serial number of operation after the completion of updating operation, then will not if updating failure
Record.Therefore it can also judge whether the update operation of corresponding node succeeds by updating the serial number of operation.
Configuring request and more new logo are sent in configuration storage server, will be matched by configuration storage server by S208
It sets request and more new logo is synchronized to other nodes of cluster.
Wherein, configuration storage service is the simple storage server for being used to storage configuration name and Configuration Values, is had
Memory can be lesser storage and be also possible to very big memory space, is different from general server, is for storage configuration
Request and this specific target of more new logo and design.
