popular or typical pmdk applications?

[Jaeho Kim]

Hi all,

 

I am looking for an application that uses pmdk appropriately. 

I have looked at the pmdk, pmdk-example and pmdkv. Is there any other example that is being actively developed or used that I can refer?

Thanks,

Jaeho

Hi Jaeho,

• The REDIS pmem storage engine reference code can be found here - https://github.com/pmem/pmem-redis
  
• "Introducing PMDK into PostgreSQL" info and proposed patches can be found here - https://www.pgcon.org/2018/schedule/events/1154.en.html
• Cassandra - https://software.intel.com/en-us/articles/making-nosql-databases-persistent-memory-aware-the-apache-cassandra-example
• More examples can be found on the Intel Developer Zone - https://software.intel.com/en-us/persistent-memory/library

In-Memory, Relational, and Key-Value Databases are a great starting place as they typically have pluggable storage engines which can be easily modified to use PMDK and Persistent Memory.  

The NOVA Filesystem (https://en.wikipedia.org/wiki/NOVA_(filesystem)) uses PMDK if you wanted something along these lines.

Thank you, Steve

It helps me a lot!

Hana database 2.0 sp3 uses pmem. Instead of storing the data on memory some tables can be stored in dax FS backed by pmem

Hi Jaeho,

you can also find:

- Storage Engine to MongoDB working on Persistent Memory: https://github.com/pmem/pmse

- Redis reference code which uses Persistent Memory as an extension of DRAM: https://github.com/pmem/redis/tree/4.0-volatile and Proof of Concept which is using this memory in persistent way: https://github.com/pmem/redis/tree/reserve_publish_poc

Thank experts, I'll check these too.

Hi Steve,

In our blogs about supporting PMEM with the Aerospike NOSQL database, we didn't mention that we're using pmem.io ( it's in passing ),

but we are, with general availability production release ( not just a fork ). https://www.aerospike.com/blog/aerospike-4-5-persistent-memory-compression/

The library module we are using is libpmem.

Although Aeropsike is an open source database, we haven't published the PMEM code. It's in our enterprise edition, currently.

Hi Brian,

I hope you don't mind my asking, but do you actually have access to real PM devices?
If so, are they on a cloud platform, or on your premises?

Steve,

I am very twitchy about my mutual NDAs with all of the companies concerned, so I regret I can't be quite as helpful as you might like.

I have access to both public cloud and non-public-cloud samples.

Why do you ask?

In addition, I read the work done by NTT Software Innovation Center on PostgresSQL with PMDK.  Here is the URL: https://www.pgcon.org/2018/schedule/attachments/507_PGCon2018_Introducing_PMDK_into_PostgreSQL.pdf    There is a recorded session of this presentation on Youtube.

In this case, NTT developers use PMDK with HPE NVDIMMs, not Intel Optane DC Persistent Memory Module.  I am eager to see the performance of Intel Optane DC Persistent Memory Module with the work done by NTT ... :)

Regards,

Otto
