Passing a *bool Pointer for AllowPartialResults in Golang's FindOptions

When working with MongoDB in Golang, you might need to use the AllowPartialResults option within the FindOptions structure to specify whether the query should return partial results if some of the shards are unavailable. This can be particularly useful in a sharded cluster environment. In this post, we'll discuss how to pass a *bool pointer to this option correctly.

Understanding AllowPartialResults

In MongoDB, the AllowPartialResults option is part of the query options that determine the behavior of your query execution. When set to true, this option allows the query to return partial results if some shards are down or unreachable. This can be vital for read-heavy applications that need to maintain high availability.

Declaring a *bool in Golang

In Golang, the AllowPartialResults field within FindOptions is of type *bool. This means it expects a pointer to a boolean value. Let's go through the steps to declare and use this field effectively.

Summary

Using the *bool pointer for AllowPartialResults in Golang's FindOptions allows you to handle partial results gracefully when querying a sharded MongoDB cluster. This capability ensures that your application remains resilient and available, even if some shards experience downtime.

By following the steps above, you'll be able to implement this option correctly in your Golang application, enhancing its robustness and reliability.
