Provide a count function about milvus-sdk-node

[shanghaikid]

if you want count, you can just count it by yourself, here is my test code, all you need is the res.data.length?

  it(`Query with data limit only`, async () => {
    const expr = 'age > 0';
    const res = await milvusClient.query({
      collection_name: COLLECTION_NAME,
      expr: expr,
      output_fields: ['age', 'meta', VECTOR_FIELD_NAME],
      limit: 3,
    });

    expect(res.data.length).toBe(3);
  });

this is perfect but only if the query is running on the server where milvus is installed, if i run it from another server all ids are transferring over the network, while i just want a count!

As far as I know, milvus doesn't provide these feature, we can do nothing more in the client(sdk), I can provide the length for you directly, but the load will still be transferred through the network.

if you don't want too much load, you can set the out_fields with only 1 field.

Maybe you can create an issue in the milvus repo.
