Querying Stream Details¶
Initialize a DIS client instance named dic. For details, see Initializing a DIS Client.
Use the DIS SDK to query the details about a specified stream.
String streamName = "myStream";
DescribeStreamRequest describeStreamRequest = new DescribeStreamRequest();
describeStreamRequest.setStreamName(streamName);
System.out.println("descStream: " + JsonUtils.objToJson(dic.describeStream(describeStreamRequest)));
The returned stream details are as follows:
descStream: {"stream_name":"myStream","create_time":1515140868451,"last_modified_time":1515140868451,"retention_period":24,"status":"RUNNING","stream_type":"ADVANCED","partitions":[{"status":"ACTIVE","partition_id":"shardId-0000000000","hash_range":"[0 : 4611686018427387902]","sequence_number_range":"[0 : 0]"},{"status":"ACTIVE","partition_id":"shardId-0000000001","hash_range":"[4611686018427387903 : 9223372036854775807]","sequence_number_range":"[0 : 0]"}],"has_more_partitions":false}
