Embodiment Construction

[0019] Full-text retrieval means that the computer index program builds an index for each word by scanning each word in the article, indicating the number and position of the word in the article. Search, and feed back the results of the search to the user's retrieval method. This process is similar to the process of looking up a word through a search word table in a dictionary. In order to illustrate the characteristics of the distributed database data migration in the present invention, Elasticsearch will be taken as an example below to illustrate the basic idea and specific implementation details of the present invention.

[0020] In a practical application environment, such as an online shopping mall system, users need to search for products on the mall, and ES can be used to store all product information and inventory information. For example, if a user needs to find a "mobile phone" product, he only needs to enter "mobile phone" Search for the products he needs to search...

Abstract

The invention provides a method for quickly and accurately migrating distributed system files. The method comprises the following steps of establishing a to-be-migrated data list, and recording a filestorage position; exporting the files by using a first exporting device; and exporting the files by using the second exporting device. The invention further provides a device for quickly and accurately migrating the distributed system files. According to the method and the device, the characteristics of different exporting devices are utilized, and the different exporting devices are combined andutilized such that the quick and accurate migration of distributed system files can be realized.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a distributed system file migration technology. Background technique [0002] Elasticsearch (ES) is a distributed and scalable real-time search and analysis engine. Using ES can realize various functions, such as distributed real-time file storage, and index each field so that it can be searched. ES is a distributed search engine for real-time analysis, which can be extended to hundreds of servers and handle PB (petabyte)-level structured or unstructured data. [0003] In the process of new system development and upgrading, data migration is sometimes required. Due to the huge amount of distributed system file data, data migration takes a long time and there are serious data loss problems. [0004] CN107943889A discloses a migration method and system between databases. First, the first database is migrated to the second database, and second, the second datab...
