How can I update a collection's description field?

[soutot]

Hi,

Reading the docs and skimming though the code, I couldn't find a way to update the description field of a collection.

I can create a collection and provide the description. I can read the description from describe_collection(). I can rename the collection using rename_collection. But I can't find a way to update the description. Tried looking into LangChain's wrapper too, but looks like they also don't have an implementation for that.

Thanks in advance

So far we don't have an interface to change a collection's description. I'll talk about it with the team. Will let you know later.

Thank you, that would be of greatly help. For now, I'm thinking of adding a description key inside the properties field instead.

The commit for "update a collection's description field" has been merged: #41547
It will be available in the next minor version(v2.5.12) of milvus so you can update a collection's description by alter_collection_properties interface like this:

client.alter_collection_properties(collection_name=collection_name, properties={"collection.description": "new desc"})

Note: the property "collection.description" cannot be deleted by client.drop_collection_properties()
