Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] A method for generating and sorting iris features of a distributed SQL database of the present invention, such as figure 1 shown, including the following steps:
[0025] Step 1: Obtain a target data sequence in the database, wherein the target data sequence includes a plurality of data elements;
[0026] Step 2: sending a query request to multiple computing nodes in the distributed SQL database, the query request carrying query items, sorting items and sorting rules;
[0027] Step 3: arbitrarily selecting a time series in the time series set as a target time series; dividing the target time series to obtain at least two time subsequences;
[0028] Step 4: dividing multiple data elements in the target data sequence into multiple subsequence groups to obtain multiple subsequences;
[0029] Step 5: Express n values containing time se...

The invention discloses an iris feature generation sorting method for a distributed SQL database, and the method comprises the steps that each calculation node queries the data of the node according to a query item, carries out the sorting of a query result according to a sorting item and a sorting rule, and generates a unique feature iris matrix through the information contained in a time sequence; the information can be used as an iris image to provide input data for a deep learning algorithm and thus providing guarantee for data mining in combination with the deep learning algorithm; the invention can further serve for feature comparison, machine learning and other data analysis and data mining methods, can be expanded to be applied to generation and reading of feature irises of other numerical values with sorting relations based on the method, and has very high practicability and wide applicability. The control node only needs to merge the ordered sequences sorted by the computingnodes to complete sorting of a large amount of data, so that IO time is greatly shortened, sorting efficiency is improved, and user experience is enhanced.
Description
technical field [0001] The invention belongs to the technical field of computer languages, and relates to a method for generating and sorting iris features of a distributed SQL database. Background technique [0002] With the development of technology, the amount of data contained in the database is getting larger and larger. Correspondingly, when the server responds to the user's query request for the database, it takes longer and longer to sort and process (or operate) the data in the database, causing the user to wait for a long time to get The sorted data sequence fed back by the server. Therefore, there is an urgent need for a method capable of efficiently sorting the data in the database. [0003] There are two types of nodes in the distributed SQL database: control nodes and computing nodes. Computing nodes are used to interact with control nodes, save fragmented data, complete local queries and local query optimization; control nodes are used to provide external qu...
