Sorry if this is already partially/completely implemented, feel free to let me know about the state of this issue in the repo.

This issue is divided in two sections, first you need to make the implementation, second you must update the code-samples (no one likes a outdated docs, right?).

New implementation

Related to:

spec: https://github.com/meilisearch/specifications/pull/258
meilisearch issue: https://github.com/meilisearch/meilisearch/issues/4052

Add a method createSnapshot similar to createDump() to call the newly introduced POST /snapshots route and return a task.

👉 Usage: https://www.notion.so/meilisearch/Usage-On-demand-snapshots-f105c94abb444b61a9d0f94550a5199e

Code samples:

Inside of this file: .code-samples.meilisearch.yml:

Create a new entry with this key create_snapshot_1: containing a call to the createSnapshot() method.

Use this as a reference if the previous description was not helpful:

create_snapshot_1: |-
  curl \
  -X POST 'http://localhost:7700/snapshots'

Todo:

[ ] Implement the new createSnapshot method
[ ] Update the code-samples according to this issue.
