Description
The present invention relates to the field of computers, and in particular, to a method, an apparatus, and a device for updating information.
In distributed file systems, data placement is typically done in a multi-copy fashion to coordinate load and failure recovery. However, there are several common ideas for the inconsistency of multiple copies of updates caused by information updates: (1) after the master copy is updated, a neighbor message forwarding mode is initiated: the updating message is transmitted to the network by forwarding to all or part of the neighbor nodes; (2) copy tree mode: the main copy is taken as a root node, when the updating message is forwarded by the neighbor nodes for the first time, an n-branch tree formed by all copy nodes is established, and the subsequent updating message is only carried out in the tree.
There are several methods for updating information of multiple copies as follows: synchronous update, asynchronous update and strong consistency asynchronous update. And (3) synchronous updating: and the number N of the copies is that the primary copy is updated firstly, then an updating command is broadcasted to all the secondary copies, and the information of successful updating is returned after the updating confirmation is returned after all the secondary copies are updated. Asynchronous updating: and the number N of the secondary copies is that the primary copy is updated firstly, then an updating command is broadcast to all the secondary copies, when any one secondary copy returns an updating confirmation, the updating success information is returned, and the other secondary copies continue asynchronous updating. Strong consistency asynchronous updating: and the number N of the copies is that the primary copy is updated firstly, then the primary copy broadcasts an updating command to the secondary copy according to the position information of the secondary copy stored in the node, and waits for copy updating confirmation, and when W is more than N/2 updating confirmations, the successful updating can be returned. And the latest data can be read only by ensuring that R (W + R > N) read returns in the subsequent process.
However, the existing information updating method needs to update the primary and secondary copies step by step, and then broadcast and update the secondary copies after the primary copies are updated, which consumes time; in addition, the broadcast mode of the update request information needs to transmit the update request information for multiple times and transmit the update request information indirectly in multiple levels, which is time-consuming, inefficient and not beneficial to providing the service of the latest data to the outside in the first time.

It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the information updating can be applied to various situations such as e-mail updating, document updating, webpage updating and the like.
The client in the embodiment of the present invention may change information and review information, and may be a mobile phone, a tablet computer, a notebook computer, a desktop computer, or the like.
The switch in the embodiment of the invention can be a switch which is responsible for sending or forwarding the information updating request information and establishing information forwarding between the client and the node, or a switch which is responsible for forwarding the change request information sent by the sender client to the corresponding node for processing.
The node in the embodiment of the present invention may be a server, and is responsible for receiving information update request information sent by the switch, and sending response information to the switch after performing corresponding processing on the copy in the node according to the information update request information, or is responsible for receiving change request information sent by the switch, and sending update success information to the switch after changing the copy in the server according to the change request information.
The information updating request information in the embodiment of the invention comprises document information changing, mail writing, webpage information changing, webpage browsing and the like.
Fig. 1 is a schematic view of a scene of information update according to an embodiment of the present invention. As shown in fig. 1, for example: when a user changes webpage information through a computer client, the exchanger receives request information for changing the webpage information sent by the client, the changed webpage information comprises the webpage information to be changed and a copy group number, the exchanger inquires a copy group information table according to the copy group number G2, and the copy group information table comprises: the method comprises the steps that a copy group number G2 and server numbers N2, N3 and N4 for storing copies are obtained by a switch, server numbers N2, N3 and N4 are obtained by the switch, the switch sends request information for changing webpage information to servers with the server numbers N2, N3 and N4, when the servers N2, N3 and N4 update stored copies according to the information updating request information, updating success information is sent to the switch, when the number of the updating success information received by the switch is half of the number of the servers N2, N3 and N4 (assuming that the updating success information of the servers N2 and N4 is received), response information corresponding to the information updating request information is sent to a computer client, and at the moment, a user can browse the changed webpage information through the computer client. And continuing to update the copy of the server N3 which does not receive the information of successful update, so that the node completes information update according to the information to be updated.
Example one
Fig. 2 is a flowchart illustrating an information updating method according to a first embodiment of the present invention in detail, where fig. 2 is a flowchart illustrating the information updating method according to the first embodiment of the present invention, and an implementation subject may be a switch in the first embodiment of the present invention, where the method specifically includes the following steps:
step 201, the switch receives an information update request message, where the information update request message includes: information to be updated and the copy group number.
The information updating request message comprises writing request information and reading request information, the writing request information is request information indicating writing operation, and the reading request information is request information indicating browsing operation.
For example, the information update request information may be to change document information, or to write a mail, or to change/add web page information, or to browse a web page, etc. The method comprises the steps of changing document information, writing mails, changing/adding webpage information and the like, wherein the request information with writing operation is summarized into writing request information, and the request information which is similar to a browsing webpage and has no writing operation but only reading operation is summarized into reading request information. The information update request information is then divided into write request information and read request information.
For example: when a user changes webpage information (writes request information) on a computer client, the client sends the request information for changing the webpage information to the switch, and the switch receives the information updating request information sent by the client.
When a plurality of users change the webpage information on a plurality of computer clients, the clients simultaneously send request information for changing the webpage information to the switch, and the switch simultaneously receives a plurality of write request information sent by the clients.
Optionally, the switch receives multiple write request messages sent by multiple clients simultaneously, and only receives the write request message sent by a first client when the multiple write request messages belong to the same copy group, where the multiple clients include the first client.
For example: the switch receives write request information of a plurality of pieces of modified webpage information sent by a plurality of clients simultaneously, when the write request information of the plurality of pieces of modified webpage information belongs to the same copy group G2, the switch only receives the request information of the modified webpage information sent by a first client, and the plurality of clients comprise the first client, namely the first client is one of the plurality of clients.
The reason why the switch receives only one client instead of request information for changing web page information sent by a plurality of clients is that it is not easy to control if a plurality of clients change the same web page at the same time. In the embodiment of the invention, a distributed lock can be installed on the switch for control, so as to control the switch to receive only the request information for changing the webpage information sent by the first client, and the first client can be a client with the highest priority in a plurality of clients by self-definition. Optionally, after the priorities of the clients are sorted, the switch receives write request information for changing the web page information sent by the clients in order through the distributed locks, and only the switch needs to be ensured to receive the write request information sent by one client at the same time.
However, the switch can receive a plurality of read request messages sent by a plurality of clients at the same time.
And step 202, the exchanger queries a copy group information table according to the copy group number to acquire a node number.
The copy group information table includes: and the corresponding relation between the copy group number and the node number. The copy set information table may be maintained within the switch.
The node may be a server; and the node number can be server code. The copy group information table is a copy group number and the copy group number corresponds to the node number of the stored copy.
For example: the switch queries a copy group information table according to the copy group number G2, wherein the copy group information table comprises: the copy group number G2 and the encodings N2, N3, and N4 of the server, obtain node numbers N2, N3, and N4. In the copy group information table shown in table one, each copy group number corresponds to a node number where a copy is stored.
Watch 1
| Duplicate group number | Node number |
| G1 | N1,N2,N3 |
| G2 | N2,N3,N4 |
| G3 | N5,N6,N7 |
| G4 | N6,N8,N9 |
| … | … |
| Gm | Ni,Nj,Nk |
And 203, the switch sends the information to be updated to the node corresponding to the node number, so that the node completes information update according to the information to be updated.
The switch sends the information to be updated to the nodes N2, N3 and N4 corresponding to the node numbers N2, N3 and N4, so that the nodes N2, N3 and N4 update the copies of the respective nodes according to the information to be updated, and receive the update success information sent by the nodes.
For example: the switch sends the information to be updated to the server N2, the server N3 and the server N4 corresponding to the server codes N2, N3 and N4, so that the server N2, the server N3 and the server N4 receive the update success information sent by the servers when the copies stored in the respective servers are updated according to the information to be updated. The server N2 updates the copy in the server N2, and after the update is successful, the server N2 sends update success information to the switch; the server N4 updates the copy in the server N4, and after the update is successful, the server N4 sends update success information to the switch. Server N3 has not yet updated the copy, and no update success information is sent to the switch.
Optionally, the nodes include a first node and a second node;
when the switch receives information updating success information sent by the first node, the first node is used as a main node; and storing the node number of the first node in the copy group information table.
For example: when the switch receives the 2 pieces of update success information sent by the server N2 and the server N4, the copies in the server N2 and the server N4 are used as primary copies; the encodings of server N2 and server N4, N2 and N4, are stored in the switch's copy group information table, which is now incremented by the node number at which the primary copy is stored. In the copy group information table after the node number is stored as shown in table two, each copy group number corresponds to the node number of the stored copy, and the node number of the stored primary copy corresponds to the node number of the stored primary copy.
Watch two
| Duplicate group number | Node number | Number of main node |
| G1 | N1,N2,N3 | N1,N2 |
| G2 | N2,N3,N4 | N2,N4 |
| G3 | N5,N6,N7 | N6,N7 |
| G4 | N6,N8,N9 | N6,N8 |
| … | … | … |
| Gm | Ni,Nj,Nk | Nx,Ny |
Optionally, after receiving the information update failure information sent by the second node, the switch instructs the first node to send the information to be updated to the second node, so that the second node completes information update according to the information to be updated.
Optionally, when the time threshold is reached, if the node does not complete updating the information to be updated, the node sends update failure information to the switch.
For example, the time threshold may be a self-defined value, such as 1 minute, after the server N3 receives the information to be updated for 1 minute, if the server N3 has not finished updating the copy, the server N3 sends update failure information to the switch, at this time, after the switch receives the information update failure information sent by the server N3, the switch instructs the server N2 or the server N4 to send the information to be updated to the server N3, specifically, the server N2 or the server N4 sends the master copy to the server N3, and the server N3 updates the copy through the obtained master copy, so that the server N3 finishes updating the information according to the information to be updated.
In the information updating method provided in the first embodiment of the present invention, an information updating request message is received by a switch, where the information updating request message includes: information to be updated and a copy group number; inquiring a copy group information table according to the copy group number to obtain a node number; and sending the information to be updated to the node corresponding to the node number, so that the node completes information updating according to the information to be updated. The information updating request information is directly forwarded to all the node numbers of the stored copies by the switch, so that the forwarding times are reduced when the information updating request information is sent, waiting is not needed, the time is saved, and the efficiency is high. The client can receive the response information in time, time consumption caused by waiting for the completion of the information updating of all the nodes is avoided, time is saved, and efficiency is high. And after information updating failure information sent by the second node is received, the first node is indicated to send the information to be updated to the second node, so that the second node completes information updating according to the information to be updated, and all nodes can complete information updating quickly and conveniently.
