This application discloses a method for scaling up nodes in a distributed search engine, including obtaining the current information of the distributed search engine cluster and the information of the scaling nodes; calculating the total number M of shards that the scaling nodes can accommodate based on the current information of the cluster and the information of the scaling nodes; adding the scaling nodes to the cluster; performing multiple rounds of node pre-allocation, each round of node pre-allocation including: establishing a weight index and dividing the weight index into N weight shards; performing data balancing on the cluster; and completing node allocation when N reaches a preset value. The solution provided by this application solves the problem in the prior art where distributed search engines cannot scale up the cluster in-situ or on demand when the cluster data capacity or data write performance reaches its limit, resulting in resource waste.

This application relates to a method, apparatus, system, device, and storage medium for intelligent driving data refeeding testing. It involves equally dividing W test datasets collected from real vehicles to obtain Z data groups, with the test datasets within each data group sorted in descending order of data size. Q domain controllers are then equally divided into Z refeeding clusters, with the domain controllers within each refeeding cluster sorted in descending order of efficiency. Component matching between the Z data groups and Z refeeding clusters is completed by assigning data groups with larger data sizes to refeeding clusters with higher overall efficiency. Furthermore, in each matched data group and refeeding cluster, the datasets within the data group are sequentially assigned to the domain controllers within the refeeding cluster, thus performing the current round of refeeding testing. This application can reduce waiting time and resource waste during the testing process, significantly improving testing efficiency.

The object of the present invention is to meet the long-felt need for a fail-safe device consuming as little data capacity as possible, which is intended to effectively implement the authentication of the caller ID and the associated telephone number at the receiver. In view of the well-established methods in the field of ISDN technology, the solution is provided by means of a data channel in the form of a strictly assigned parallel authentication network consisting of a plurality of interfaces, which cannot provide any additional data payload in addition to the purpose of authentication. Limiting the data packets that can be received to always a few bytes and the responses that can be emitted to always a few bits enables a high degree of redundancy and allows implementation in the form of a system-related security component.

This invention discloses an intelligent performance appraisal system and method. In the field of performance appraisal management technology, this invention exhibits unique advantages in data security through its innovative segmentation and encryption processing mechanism. It generates sequence codes based on partition feature assignment columns and data capacity, and then dynamically generates encryption codes by combining data arrangement positions. Differential segmentation of data segments is achieved through ratio columns, which not only closely links the capacity allocation of each data segment with the encryption code, but also processes data segments with the same ratio through position marking, forming a dynamic and unique layer of encryption protection. This encryption method is deeply bound to the data's own attributes and storage location, greatly increasing the difficulty of unauthorized data cracking and effectively ensuring the security of sensitive performance data.
