Embodiment 1

[0105] Figure 7 is a flowchart of a method for adjusting metadata between two metadata clusters according to an optional embodiment of the present invention, such as Figure 7 As shown, taking a system with two metadata clusters as an example, the steps of the planning-based metadata adjustment method include:

[0106]Steps S702-S704: The client or the gateway responsible for distributing client messages accesses the server nodes in the metadata cluster 1 and the metadata cluster 2 according to the metadata distribution rule.

[0107] Step S706: The system administrator adjusts the metadata distribution rules, and according to the system triggering method: automatic, manual, timing after triggering; after the distribution rules are adjusted, a metadata redistribution request is sent to the metadata redistribution device in the system.

[0108] Step S708 : The metadata redistribution device analyzes the metadata distribution rules before and after adjustment, and obtains the ...

Abstract

The invention provides a metadata migration method and a metadata migration device in a distributed system, wherein the metadata migration method comprises the steps of receiving a notification message from the distributed system, wherein the notification message is used for indicating change of a metadata distribution routing rule; comparing the metadata distribution routing rule before adjustment with the adjusted metadata distribution routing rule according to the notification message, and obtaining a migration data flow of the metadata between the nodes of a metadata server cluster, wherein the migration data flow is used for indicating the migration process of the metadata. The metadata migration method and the metadata migration device settle a problem of requirement for partition or migration of partial metadata to one or a plurality of metadata server clusters and synchronous modification of affected metadata routing rule in adjusting the metadata routing rule in related technology.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a metadata migration method and device in a distributed system. Background technique [0002] After the client request message arrives at the border gateway processing the client request message in the distributed system, the border gateway needs to first locate the metadata server according to a certain method, and then the metadata server queries its own database to route the message to the next-level metadata server or Route to the server that stores the real data. In the above process of locating the metadata server, two solutions are generally adopted in related technologies: pre-configuring the routing information of the metadata or creating an internal database by the system to maintain the routing comparison relationship between query conditions and the metadata server. However, with the increase of stored data, the operation of querying the comparison relationship wil...
