Query Cache Architecture


The query cache consists of cache storage space, cache metadata, and cache detection in query compilation.

The process of accessing the cache metadata is very fast. If the metadata shows a cache hit, the bulk of the query processing is eliminated, and the results are immediately returned to the user. The process of adding the new results to the cache is independent of the results being returned to the user; the only effect on the running query is the resources consumed in the process of writing the cached results.
