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.

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()
);

await milvusClient.GetCollection("book").DropPartitionsAsync("novel");
