Abstract

The invention provides a lossless recovery distributed multi-language retrieval platform and a lossless recovery distributed multi-language retrieval method. The lossless recovery distributed multilingual retrieval platform comprises a main node and distributed nodes communicating with the main node, wherein the main node and the distributed nodes are respectively and correspondingly connected with an external storage device, and the external storage device is configured to store data and memory states received by the main node or the distributed nodes connected with the external storage device at preset time intervals; when a fault is recovered, data in the external storage device is directly recovered to a local memory, the data is adjusted, and a routing algorithm is operated to enablethe routing algorithm to point to a new node; the main node is configured to issue multilingual data meeting retrieval conditions to the distributed nodes; the distributed nodes are configured to query multilingual data meeting retrieval conditions in a hotspot index table of an index memory cache layer; and multilingual data of which the access frequency is not less than a preset access frequencythreshold exists in the hotspot index table.

Description

technical field [0001] The disclosure belongs to the field of multilingual big data processing, and in particular relates to a non-destructive recovery distributed multilingual retrieval platform and a method thereof. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] On the premise of ensuring efficient computing, correct results and real-time response, the high availability of the system must be guaranteed, that is, when a failure occurs, implement the fastest, user-insensitive failure recovery and continuous service. The inventors have found that the existing stream data processing engine failure recovery mechanism still has serious defects, which may cause data loss. In addition, when searching for massive big data, it is necessary to scan the entire table or access multiple disks, which reduces the query speed of the index table. Con...
