Scale Tests

Goal

Scale tests are designed to check the scalability of Milvus.

For instance, if the dataNode pod expands from one to two:

  • verify the consistency of existing data

  • verify that the DDL and DML operation is working

Prerequisite

Test Scenarios

Milvus in cluster mode

  • scale dataNode replicas

  • expand / shrink indexNode replicas

  • scale queryNode replicas

  • scale proxy replicas

How it works

  • Milvus scales the number of pods in a deployment based on the milvus operator

  • Scale test decouple the milvus deployment from the test code

  • Each test scenario is carried out along the process:
    deploy milvus -> operate milvus -> scale milvus -> verify milvus

  • Milvus deployment and milvus scaling are designed in ./customize/milvus_operator.py

Run

Manually

Run a single test scenario manually(take scale dataNode as instance):

  • update update milvus image tag IMAGE_TAG in scale/constants.py

  • run the commands below:

  cd /milvus/tests/python_client/scale  
  
  pytest test_data_node_scale.py::TestDataNodeScale::test_expand_data_node -v -s
