Amazon classifies every particular person product inside its catalog into numerical classes generally referred to as “nodes.” These nodes are then organized in a significant and hierarchical method reflecting “dad or mum nodes” and “leaf nodes.” A leaf node is a extra exact and extra particular sub-category of the dad or mum node. In different phrases, dad or mum nodes characterize essentially the most normal classification of merchandise and every leaf or “youngster” mirror a particular and related subdivision. For instance, node 283155 is the dad or mum node for “books,” and node 5 displays “laptop & expertise books” — a particular type of e book. On this instance, 283155 is the dad or mum and 5 is the kid or leaf. At the moment, Amazon boasts 100,000+ nodes. Nonetheless, lots of them are both inaccessible by the API or don’t comprise sensible data.

The method of discovering all of Amazon’s nodes is carried out by repeated API requests. A minimal of 1 second ought to cross between every distinctive request for many associates.

At this level, each row within the SampleNode_US desk runs by the API as soon as once more. However this time the aim is to find out every row’s ancestor. Duplicate ancestors from returned API knowledge are eliminated and the outcomes are then added to their very own database desk, RootNode_US. On this method, the basis BrowseNode containing all mother and father is found by structuring the ensuing knowledge returned from the API.

Lastly, every row within the RootNode_US tables will get handed by the API to be able to get hold of youngsters Browse Node IDs. Every youngster BrowseNode, in flip, is also handed to the API seeking deeper youngsters. When no extra youngsters could be discovered, then the subsequent dad or mum node or youngster is loaded and run although. The method repeats till every node has been explored for all their youngsters. Outcomes are saved and/or up to date within the Node_US desk. It takes about 2-3 weeks for the script to parse all nodes after factoring within the required time delay between API requests.
