OrientDB on ZFS filesystem

[Carlo Pradissitto]

Hi,

I just finished a preliminary performance analysis:

If someone from Orient Technologies wants give me some indication, I'll be happy to collaborate for a deeper research.

Hi,

Thank you, this is very interesting.

I'm only a user here but I have a system that deals with millions of records daily and one of my impediments right now is disk usage.

I'm sorry that I can not hand over the data (classified) but I could run your test on 10-20 million vertices + connecting edges.

Anyways... this looks like a thorough test and is appreciated!

Regards,

Hi Stefan,

I hope that my work can be useful for you, as well as for the community.

Anyway, if you have a question, or a suggestion, I'll be pleased to answer, as far as I can

Thanks!

Hi Luca,

I hope it will be useful, for you and for the community

If you have a bigger database for testing, and a set of related queries (search, insert, update, delete, ..., traverse), I'll try to make a "real world" analysis, as soon as I can.

See you

C

Hi,

Could you perhaps create a summary for setting up the filesystem in the correct way?

I'm not a seasoned Linux/Ubuntu user but I should be able to manage :).

Hi Stefan

What I've read in that very good blog post - is that this runs on ZFS / Solars - not Linux / Ubuntu.

So you may use - Oracle Solaris 11.1  or   OpenIndiana - or even better SmartOS  or OmnioOS (if you like an installed OS) depending on your needs.

FreeBSD ist too a possibility.

I'm really not sure if ZFS on Linux (FUSE) does give you the same performance metrics as written here.

Regards 

Michael

OK thanks, I'm just going to pretend I knew that :).

Hi Stefan,

I haven't yet done any load test in Linux environment, and If I do, it will be using ext4, though I'm following the OpenZFS project:

http://open-zfs.org/wiki/Main_Page

Nowadays I'm concentrated on ZFS because we are seriously evaluating to deploy our OrientDB graph, when ready for production, in a SmartOS farm.
