search data space, and divide it into the KD tree and R tree according to the overlapping. KD trees are a kind of non-overlapping space division.a three-dimensional K-D tree. The First Division (red) divides the root node (white) into two nodes, which are then divided (green) into two sub-nodes, respectively. Each of the last four child nodes is divided (blue) into two child nodes. Because there is no further division, the last eight nodes are called leaf nodes. kd Tree Build: KD tree is

KD trees are a kind of non-overlapping space division.a three-dimensional K-D tree. The First Division (red) divides the root node (white) into two nodes.

This layer is the focus and will be described in more detail later. KV Layer Provides a transactional (distributed/stand-alone) storage, between the KV layer and the SQL layer, there is a layer of ab

Brief introductionBecause of the shortcomings of traditional relational database in distributed environment, the concept of NoSQL has gradually become the focus of the industry in recent years, and more and more technical staff are accustomed to using NoSQL database for daily development, and SAE has also carried out the research and development of NoSQL in order to deal with this new demand.KV DB is a distributed Key-value data storage service developed by SAE to support massive key-value stora

A sstable file can be viewed as a disk-based, read-only map that supports sequential scanning and can look for a key.

Https://pingcap.com/blog-tidb-internal-2-zh Here we simply understand the relational model as table and SQL statements, then the question becomes how to save the table on the KV structure and how to run the SQL statement on the KV structure. Let's say we have a definition for this table: CREATE TABLE User { id int, Name varchar (), Role varchar (), age int, PRIMA

The precedence queue (priority_queue) is consistent with the function interface of the general queue (queue), and, in contrast, the priority queue is the smallest (or largest) element in the entire queue each time it is queued. This paper briefly introduces a priority queue based on an array two-fork heap, defines the data structure and implements the function interface as follows: One, the key value pairs the structure body: keyvalue Copy Code code as follows: =============keyv
