Mingliang Liu updated HDFS-15025: --------------------------------- Release Note: Add a new storage type NVDIMM and a new storage policy ALL_NVDIMM for HDFS. The NVDIMM storage type is for non-volatile random-access memory storage medias whose data survives when DataNode restarts. (was: Adding the new storage media NVDIMM and ALL_NVDIMM storage policy on HDFS,including the test code for them) > Applying NVDIMM storage media to HDFS > ------------------------------------- > > Key: HDFS-15025 > URL: https://issues.apache.org/jira/browse/HDFS-15025 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, hdfs > Reporter: YaYun Wang > Assignee: YaYun Wang > Priority: Major > Labels: pull-request-available > Fix For: 3.4.0 > > Attachments: Applying NVDIMM to HDFS.pdf, HDFS-15025.001.patch, > HDFS-15025.002.patch, HDFS-15025.003.patch, HDFS-15025.004.patch, > HDFS-15025.005.patch, HDFS-15025.006.patch, NVDIMM_patch(WIP).patch > > Time Spent: 12h 10m > Remaining Estimate: 0h > > The non-volatile memory NVDIMM is faster than SSD, it can be used > simultaneously with RAM, DISK, SSD.
