Ref https://github.com/milvus-io/milvus/issues/42148 This PR supports create index for vector array (now, only for `DataType.FLOAT_VECTOR`) and search on it. The index type supported in this PR is `EMB_LIST_HNSW` and the metric type is `MAX_SIM` only. The way to use it: ```python milvus_client = MilvusClient("xxx:19530") schema = milvus_client.create_schema(enable_dynamic_field=True, auto_id=True) ... struct_schema = milvus_client.create_struct_array_field_schema("struct_array_field") ... struct_schema.add_field("struct_float_vec", DataType.ARRAY_OF_VECTOR, element_type=DataType.FLOAT_VECTOR, dim=128, max_capacity=1000) ... schema.add_struct_array_field(struct_schema) index_params = milvus_client.prepare_index_params() index_params.add_index(field_name="struct_float_vec", index_type="EMB_LIST_HNSW", metric_type="MAX_SIM", index_params={"nlist": 128}) ... milvus_client.create_index(COLLECTION_NAME, schema=schema, index_params=index_params) ``` Note: This PR uses `Lims` to convey offsets of the vector array to knowhere where vectors of multiple vector arrays are concatenated and we need offsets to specify which vectors belong to which vector array. --------- Signed-off-by: SpadeA <tangchenjie1210@gmail.com> Signed-off-by: SpadeA-Tang <tangchenjie1210@gmail.com>

Installing Dependencies
Troubleshooting Docker and Docker Compose
- Confirm that Docker Daemon is running：
$ docker info
-
Ensure that Docker is installed. Refer to the official installation instructions for Docker CE/EE.
-
Start the Docker Daemon if it is not already started.
-
To run Docker without
rootprivileges, create a user group labeleddocker, then add a user to the group withsudo usermod -aG docker $USER. Log out and log back into the terminal for the changes to take effect. For more information, see the official Docker documentation for Managing Docker as a Non-Root User.
- Check the version of Docker-Compose
$ docker compose version
docker compose version 1.25.5, build 8a1c60f6
docker-py version: 4.1.0
CPython version: 3.7.5
OpenSSL version: OpenSSL 1.1.1f 31 Mar 2020
- To install Docker-Compose, see Install Docker Compose
Install jq
Install kubectl
Install helm
- Refer to https://helm.sh/docs/intro/install/
Install kind
