Collection Alias

This topic describes how to manage collection aliases. Milvus supports specifying a unique alias for a collection.

The following example is based on the alias publication.

Create a collection alias

Specify an alias for a collection.

from pymilvus import utility
utility.create_alias(
  collection_name = "book",
  alias = "publication"
)

await milvusClient.createAlias({
  collection_name: "book",
  alias: "publication",
});

// This function is under active development on the GO client.

milvusClient.createAlias(
  CreateAliasParam.newBuilder()
    .withCollectionName("book")
    .withAlias("publication")
    .build()
);

await milvusClient.CreateAliasAsync("book", "publication");

Drop a collection alias

Drop a specified alias.

from pymilvus import utility
utility.drop_alias(alias = "publication")

await milvusClient.dropAlias({
  alias: "publication",
});

client.DropAlias(context.Background(), "publication")

milvusClient.dropAlias(
  DropAliasParam.newBuilder()
    .withAlias("publication")
    .build()
);

await milvusClient.DropAliasAsync("publication");

Alter a collection alias

Alter an existing alias to another collection. The following example is based on the situation that the alias publication was originally created for another collection.

from pymilvus import utility
utility.alter_alias(
  collection_name = "book",
  alias = "publication"
)

await milvusClient.alterAlias({
  collection_name: "book",
  alias: "publication",
});

client.AlterAlias(context.Background(), "book", "publication")

milvusClient.alterAlias(
  AlterAliasParam.newBuilder()
    .withCollectionName("book")
    .withAlias("publication")
    .build()
);

await milvusClient.AlterAliasAsync("book", "publication");
