[GitHub] [nifi] tmenjo opened a new pull request #4823: NIFI-8219: PMEM-backed Repositories
tmenjo opened a new pull request #4823:
URL: https://github.com/apache/nifi/pull/4823
#### Description of PR
(See also https://issues.apache.org/jira/browse/NIFI-8219)
*Persistent memory (PMEM) is non-volatile and byte-addressable memory installed into DIMM slots. With Filesystem DAX (Direct Access) and PMDK (Persistent Memory Development Kit), a program can map on-PMEM files to userspace then read and write its data, bypassing page caches. These technologies could bring you better I/O performance than traditional disks.*
*I would propose a patchset which lets FlowFile, Content, and Provenance Repositories use PMDK (via JNI) to write their data to their files shown as follows:*
* *FlowFile Repository: Journals (.journal)*
* *Content Repository: Content/Resource Claims*
* *Provenance Repository: Provenance logs (.prov) and ToCs (.toc)*

This PR depends on libpmem in PMDK[1]. I'd say we need libpmem-devel package if we let the ci-workflow build this PR successfully.
