The invention discloses a product configuration method. The method comprises the following steps of: when a product configuration request is received, entering a feeding node on the basis of the product configuration request; calling a workflow engine interface in the feeding node so as to read a workflow in a preset resource pool and then determine a to-be-called node through the workflow, and providing an interface corresponding to the to-be-called node; and if the to-be-called node is not a closure node, obtaining a product configuration parameter from the resource pool, transferring the product configuration parameter to the interface of the to-be-called node until the to-be-called node is a signed node, and carrying out product configuration in the signed node. The invention furthermore discloses product configuration equipment and a computer readable storage medium. According to the product configuration method and equipment and the computer readable storage medium, the product configuration intelligence is improved and the product configuration maintenance cost is reduced.

The invention discloses a data backup device. The data backup device includes: a detection module for detecting operation instructions corresponding to the data of a full data set in a mobile terminal; an acquisition module for obtaining pre-backup data in the mobile terminal Set and full data set; change module, used to change the measurement value of the full data set and the index of the pre-backup data set according to the operation instruction, wherein the measurement value represents the change status of the data in the full data set, and the index is used to identify the full data set the data in; a backup module, configured to back up the data corresponding to the index in the pre-backup data set if the measurement value is greater than a preset threshold. The invention also discloses a data backup method. The invention realizes the fine-grained incremental backup method based on the measurement value, controls the amount of data backed up and the backup frequency according to the measurement value, adopts the incremental backup method to avoid redundant storage of data, reduces the cost of data backup, and improves the efficiency of data backup .

The present invention is applicable to the technical field of geographic information, and provides a spatial vector data indexing and query method based on HBase distributed storage. The method includes: establishing a spatial database metatable, and each record in the spatial database metatable corresponds to a spatial vector Data set table; each server node queries the space vector data set table according to the query conditions, and returns the query results to the client. The invention uses the RowKey index composed of partitions, spaces, attributes, object IDs, etc., which can effectively improve the organization of vector space data, thereby avoiding redundant storage of data; at the same time, it also customizes the partition strategy, which can automatically and evenly distribute data to each On the server node, the resource utilization rate of each node of the cluster is relatively balanced; in addition, the present invention also adopts a spatial coding method based on the XZ-Ordering idea, which can effectively solve the problem of line and area elements crossing geographic grids.

This application discloses a method for compressing and decompressing frozen electric quantity data of a smart meter, only needing to set key time point labels, adopting a difference method to avoid redundant storage of repeated data, and using carry data to process electric quantity data to further save It reduces the storage space and simplifies the complexity of the calculation process of decompression, thereby improving the reliability and search efficiency of data storage, and greatly reducing the space occupied by the data storage of electric energy meters, which solves the problem of freezing of electric energy meters in the existing storage Power data requires a large amount of storage space and access speed technical issues.

The present disclosure provides a massive image processing method, a massive image processing device, an electronic device, and a computer-readable storage medium, and relates to the technical field of data processing. The method includes: acquiring a matrix corresponding to multiple channels of each image in the massive image, and Carry out bitwise layering to each said matrix; store the picture bit layer data corresponding to each said channel after bitwise layering according to an inverted index structure, and generate a layer index record file; according to said layer index The record file decodes all the layer indexes of the picture, and synthesizes the picture according to the decoding result. The method can reduce the amount of image storage and improve the efficiency of image transmission.

The invention relates to an interpretation conclusion compression storage method. Fields of interpretation conclusion types are set in interpretation conclusions. The interpretation conclusion compression storage method comprises the steps of judging whether the interpretation conclusion type in the current interpretation conclusion is the same as the interpretation conclusion type in the previousinterpretation conclusion or not; and when the interpretation conclusion type in the current interpretation conclusion is different from the interpretation conclusion type in the previous interpretation conclusion, storing the current interpretation conclusion. According to the interpretation conclusion compression storage method, the integrity of the interpretation conclusion is ensured; the redundant storage of a large amount of unchanged interpretation conclusions is avoided; the storage space is saved; and the subsequent processing of the interpretation conclusions is facilitated.

The embodiment of the invention provides a distributed cache method and system. The method comprises the following step: determining a first cache node according to a primary key value of metadata, and determining a second cache node according to a secondary key value of the metadatathe; and storing metadata issued by center storage node in the first cache node and storing index position of the metadata in the second cache node, wherein the index position of the metadata is used for indicating addresses of the first cache node. According to the invention, the access of the metadata can be achieved by the index position of the metadata, so that the same metadate stored in a plurality of cache nodes is avoided, thereby avoiding redundant storage of the metadata, saving storage space and ensuring the data access consistency.

A method of low-redundancy e-mail handling, wherein: e-mail data is selected, attachments of e-mails comprised in the e- mail data are detached, stored and replaced with references accordingly, and wherein further e-mail threads comprised in the e-mail data are identified and split in separate e-mails, duplicates of e-mails are deleted while maintaining their e- mail references, differences between a first e-mail and an immediately preceding second e-mail of the same thread are identified, generating difference data, the first e-mail is replaced by the difference data, and a reference to the second e-mail is inserted therein, the e-mails and references to their predecessors and successors in the same thread are stored in a data storage, and a graph-based interface is generated for the stored e-mails and references, and an e-mail server computer device, e-mail client computer device, data processing program, computer program product, and computer data signal therefor.
