Drop Partitions

This topic describes how to drop a partition in a specified collection.

  •   You have to release the partition before you drop it.
  •   Dropping a partition irreversibly deletes all data within it.

When interacting with Milvus using Python code, you have the flexibility to choose between PyMilvus and MilvusClient (new). For more information, refer to Python SDK.

Python Java GO Node.js 
from pymilvus import Collection
collection.drop_partition("novel")

await milvusClient.dropPartition({
  collection_name: "book",
  partition_name: "novel",
});

err := milvusClient.DropPartition(
  context.Background(),   // ctx
  "book",                 // CollectionName
  "novel",                // partitionName
)
if err != nil {
  log.Fatal("fail to drop partition:", err.Error())
}

milvusClient.dropPartition(
  DropPartitionParam.newBuilder()
    .withCollectionName("book")
    .withPartitionName("novel")
    .build()
);
