Code Review
This pull request addresses a potential infinite recursion issue within the _insert method. When a SchemaMismatch error occurs for reasons other than a stale cache, the previous implementation could lead to an endless loop. The fix introduces a collection_cache parameter to control cache usage during insertion and ensures that a retry is attempted only once with the cache disabled. This is a solid approach that effectively prevents the infinite recursion. My review includes a minor suggestion to improve code clarity in the recursive call.

For better code clarity and to maintain type consistency for the promise variable, it would be better to await the result of the recursive call to _insert. While returning the promise directly works, awaiting it makes the flow more explicit and easier to follow, ensuring that the promise variable consistently holds a MutationResult object rather than switching between MutationResult and Promise<MutationResult>.
| promise = this._insert(data, upsert, false); | |
| promise = await this._insert(data, upsert, false); |

I think you can use await client.insert({
...,
skip_check_schema: true
}) |
If insert/upsert ends up with SchemaMismatch for some reason other than cached collection description, this method will be trapped in an infinite recursion, and finally crash with OOM.
In my case, if my project was bundled with ncc, the grpc part would be somehow corrupted.
