collection.has_partition("novel")
await milvusClient.partitionManager.hasPartition({
  collection_name: "book",
  partition_name: "novel",
});
hasPar, err := milvusClient.HasPartition(
  context.Background(),   // ctx
  "book",                 // CollectionName
  "novel",                // partitionName
)
if err != nil {
  log.Fatal("failed to check the partition:", err.Error())
}
log.Println(hasPar)
R<Boolean> respHasPartition = milvusClient.hasPartition(
  HasPartitionParam.newBuilder()
    .withCollectionName("book")
    .withPartitionName("novel")
    .build()
);
if (respHasPartition.getData() == Boolean.TRUE) {
