In the previous article, we already know how to store the data in the index and how to retrieve it. But we're masking the technical details of the specific implementation of data storage into the cluster and getting data from the cluster (but we glossed over many technical details surrounding how the data is distributed and Fetched from the cluster). 1. Routing documents into shards (Routing a document to a Shard) When you index a document, it is stor

Label:In the actual application, the result set of the database query is usually saved to memcached, the next access is obtained directly from the memcached, and the database query operation is not done.This can reduce the burden on the database to a large extent. SQL statements are typicallyMD5The value after () as a unique identifierKey. Below is an example of using memcached to cache a result set of a database query (this snippet immediately follows the example code):Copy the code code as fol
