[!WARNING] Since this is a release candidate (RC), we do NOT recommend using it in a production environment. Is something not working as expected? We welcome bug reports and feedback about new features.

Meilisearch v1.12 introduces huge improvements regarding indexing speed. The team worked hard to divise time to import huge datasets by two. You can also customize your settings to adapt your indexing needs and so, the indexing speed that fits your usage.

New features and updates 🔥

Improve indexing speed

Indexing time for huge dataset import (multiple millions of documents) is divided by two!

Done by @dureuill, @ManyTheFish, and @Kerollmops in #4900.

More visibility around indexing tasks

In order to give more visibility around indexing processing around your task, especially when indexing big documents, new routes have been introduced:

• GET /batches/:uid: returns a specific batch object
• GET /batches: return a list of batch objects

The same query parameters than GET /tasks route can be used to apply filtering.

Also, a new field is introduced in the task object: batch.

Done by @irevoire in #5060, #5070, #5080

Other improvements

• Introduce the reverse query parameter for GET /tasks route set to false by default. If set to true, then the tasks will be returned in reversed order (the oldest first). Done by @irevoire in #5048.
