CollectionInfo

This class holds summary information about a single collection in a list result. ListCollectionsResponse::CollectionInfos() returns a CollectionsInfo value, which is a type alias for std::vector<CollectionInfo>.

CollectionInfo();
CollectionInfo(std::string collection_name, int64_t collection_id, uint64_t create_time);

using CollectionsInfo = std::vector<CollectionInfo>;

METHODS:

• const std::string& Name() const

  Name of the collection.

• int64_t ID() const

  Server-assigned internal ID of the collection.

• uint64_t CreatedTime() const

  UTC timestamp (microseconds) when the collection was created.

• uint64_t MemoryPercentage() const

  Deprecated. Always returns 0. Use GetLoadState() to check the load progress instead.

Example

#include <milvus/MilvusClientV2.h>
using namespace milvus;

auto client = MilvusClientV2::Create();
client->Connect(ConnectParam("http://localhost:19530").WithToken("root:Milvus"));

ListCollectionsResponse response;
auto status = client->ListCollections(
    ListCollectionsRequest().WithDatabaseName("default"),
    response);
if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
}

const CollectionsInfo& infos = response.CollectionInfos();
for (const auto& info : infos) {
    std::cout << "Name:    " << info.Name() << "\n"
              << "ID:      " << info.ID() << "\n"
              << "Created: " << info.CreatedTime() << "\n";
