No bulk write function

[ktjd123]

Hi,

Is there planned release date for bulkWrite function expose?

Saw it will be exposed at end of 2022 but seems no update.

Thank you.

Hi @ktjd123, apologies for the delay on the bulk write feature. We are currently working on designing/implementing an improved bulk write API for all of the MongoDB drivers, so we are waiting until that work is done to add bulk write to the Rust driver. We do not currently have a time frame for when that will be released, but you can follow RUST-1282 for updates.

I should have researched this before migrating a nodejs app to Rust.
The app performs several updateOne operations per bulk request and doing that one by one over the wire is much slower.

How can we help this feature get prioritized/done?

[isabelatkinson]

@danielsan the bulk write feature is nearing completion and should be released within the coming weeks. Please note that the actual server command that it uses is introduced in server version 8.0, which is only available as a release candidate right now.

In the meantime, you can use the run_command method to send an update operation with multiple updates in the updates array.

Bulk write will be released in the upcoming 3.0.0-beta release, going to close this out.

Would you mind clarifying if v8 is needed for bulk writes to the same collection as well:

Starting in MongoDB 8.0, you can use the new bulkWrite command to perform many insert, update, and delete operations on multiple collections in one request. The existing db.collection.bulkWrite() method only allows you to modify one collection in one request.

Specifically, I see the mongodb docs.rs only mention a requirement of 3.6+.

Hey @ShaunSHamilton, 8.0 is required for any kind of bulk write using the bulk_write method, regardless of how many namespaces are being written to. The Rust driver does not implement the db.collection.bulkWrite() method that the docs you quoted refer to.
