In mathematical...

- Search tree (section Searching for a specific key)tree algorithm uses the key from the key–value pair to find a location, and then the application stores the entire key–value pair at that particular location...

LSM trees maintain data in two or more separate structures, each of...- than Key-Value Store because OKVS allow to build higher level abstractions without the need to do full scans. An OKVS will keep the key-value pairs sorted...
