Problems solved by technology

However, the scale of the archive stream data storage system is large, and there are problems of high failure rate and large scale of data to be recovered. The traditional logical serial data recovery method is difficult to meet the data recovery needs of large-scale systems, so a new data recovery method is needed.

Embodiment Construction

[0045] specific implementation plan

[0046] figure 1 It is an overall flow chart of the present invention, which is specifically divided into the following steps:

[0047] 1. Build a loading pool and an archive pool.

[0048] 2. Generate MiniRDB periodically and store MiniRDB in the archive pool.

[0049] 3. Use the parallel distribution recovery method to restore MiniRDB.

[0050] figure 2 It is a structural diagram of the database cluster in the loading pool designed in the first step of the present invention; the loading pool used for real-time storage of archive stream data is composed of multiple database clusters connected in series. Each database cluster consists of a group of mutual backup database nodes and a coordinating node connected through Ethernet. The coordinator node is a computer that distributes the user's loading request to all database nodes according to the load balancing strategy, and forwards the user's query request to a certain database node. ...

Abstract

The invention discloses a storage method of mass filling stream data, aiming at solving the storage of mass filing stream data and improving the management scale, access performance and reliability of the filling stream data according to the characteristics of filling stream data. The technical scheme is as follows: firstly building a loading pool which stores the filing stream data generated at high speed in real time and a filing pool which stores larger-scale filing data transferred from the loading pool; periodically generating read-only database file MiniRDB and storing MiniRDB into the filing pool; and when nodes of a plurality of filing databases in the filing pool are in fault, adopting a parallel distributed recovery method for recovering. Compared with the prior art, by adopting the invention, the scale of data capable of being stored and managed is larger, the storage and enquiry performances of data are higher, and the reliability of data is higher.

Description

technical field [0001] The invention relates to a data storage method in the computer field, in particular to a method for storing massive archiving flow data based on a computer cluster system. Background technique [0002] With the development of computer network and storage technology, a new demand for mass data storage and analysis has emerged in many fields such as network security management, network search, communication, finance, and scientific experiments. Data, and mining the regular knowledge hidden in this type of data. For example, in network security applications, real-time storage, query and analysis of network communication packet header information is a common network security management method. Generation, the generation speed is fast (the number of messages generated by an ordinary Gbit network connection can reach 100,000 per second, and its data generation speed can reach dozens of MB per second), so the formed system is large in scale. Similar applica...
