Performance of Apache Ozone on NVMeconcerns Ozone Manager Ozone Client Datanode Storage Container Manager Recon Foreground Background No background load Datanode Datanode Datanode hadoop-hdds hadoop-ozone Scale out No to preserve simplicity of IO path. Ozone scales! Does background scale up and scale out? • Datanode count can scale beyond HDFS • No memory pressure on OM due to block reports/object counts/heap Much higher density per Datanode than HDFS Datanode scales out and scale up • Testbed used: • ~400 TB/Datanode • Tested with 200k containers per datanode => 1 PB per datanode. • Cisco UCS M6 • Capacity0 码力 | 34 页 | 2.21 MB | 1 年前3- HBase Practice At XiaoMifailure since each datanode need to handle too many streams.
