发布日期：十一月 17, 2020
Azure HDInsight now supports Premium Azure Data Lake Storage Gen2 for accelerated writes HDInsight HBase cluster.
- Improve your Apache HBase and Phoenix write performance by up to 9 times.
- Increased read performance.
- Premium tier offers significantly lower storage latencies as compared to other tiers, and cost savings for workloads that are transaction heavy.
The accelerated writes feature in the HDInsight HBase cluster attaches a Premium SSD managed disk to every region server (worker node). Write ahead logs are configured to be written to Hadoop Distributed File System (HDFS) mounted on premium managed disks instead of standard Azure page blobs. Premium managed disks are SSD-based and offer excellent I/O performance with fault tolerance. Using premium managed disks for WALs allows us to separate write ahead log storage from Apache HBase data storage.
With Premium Azure Data Lake Storage Gen2 support for accelerated writes HDInsight HBase cluster, customers can now have increased read performance compared to standard storage and also take advantage of Hierarchical namespace feature of Azure Data Lake Storage Gen2.
