MongoDB on-demand materialized views

php editor Zimo brings you an introduction to MongoDB on-demand materialized views. As a non-relational database, MongoDB provides the function of materialized views, which can store query results in the form of views in the database according to actual needs, improving query performance and flexibility. This feature of on-demand materialized views allows developers to dynamically create and update views based on business needs to meet different query needs. In this article, we will delve into the principles and usage of MongoDB on-demand materialized views to help readers better utilize this feature to optimize database performance.

Question content

Does the golang mongo driver support materialized views? https://www.php.cn/link/05751401fb782aa43ddf0bc31c121b7b

Solution

I'm not sure I understand the question, although I think the answer to the question is "Yes, driver support it". As of this writing, everything in MongoDB is ultimately backed by collections. Perhaps the additional context provided below will clarify further.

The key thing to note here is that there is currently no special "materialized view" object in MongoDB. have:

• gather
• Views , which are collections of valid aggregation pipeline definitions stored in the database and executed dynamically when queries against the views are executed.
• "On-demand materialized view" is a technology that uses $out or $merge to update a collection.

Regarding the last point, you can see references to this directly on [linked page], for example:

So the driver has nothing special to support. The driver will interact with supported collections.
