You can also use ZooKeeper to increment the id for distributed systems. If we're talking about a lot of inserts per second, you can increment by a thousand. For example system-A gets id range for 1-1000, system-B gets id range for 1001

That is awesome, what do you get with writes? (rw=write)
513.
by olavgg 10y ago
Same thing with Grails, though they've improved support for Angular lately. I prefer vanilla js anyway, its what I used 15 years ago, and it is what I will continue to use the next 15 years and hopefully a lot longer.

How many iops do you get when you test it with fio ( http://linux.die.net/man/1/fio ) ? Example: sudo fio --filename=/home/olav/testfile --direct=1 --sync=1 --rw=read --bs=4k --numjobs=8 --iodepth=32

If these could fit in a 1u chassis on a PCIe slot without a bracket, that would be awesome!

What about performance, have you benchmarked this? Java 7 was in my experience 50% slower on FreeBSD.

Could you not use Groovy for this? Using Groovy isn't harder than using another third-party library.

Have you guys thought about giving Windows ZFS volumes over iSCSI and then take ZFS snapshots? For example with SQL Server, it should be possible to talk to the SQL Writer Service and create a consistent database snapshot of a live SQL Serv
519.
by olavgg 10y ago
Yes, if they have ZFS too, it is basically snapshot, send & receive. Or you can clone it and rsync it to them. Do not try to snapshot a running database though. Before you execute the snapshot you should make sure everything is flushed
520.
by olavgg 10y ago
ZFS is excellent for database development! Create a snapshot before you try something that mess up your data and instantly restore it! If your development database is a few gigabytes, this will save you a lot of time.

The latest OCZ Trion series at least honor O_DSYNC correctly. You get shitty write performance, but it is the same for Samsung 950 Pro. The read performance is another story for OCZ though :( Anyway enterprise SSD's have so much overal

There may be other reasons that we are not aware of, anyway learning how to build your own vfs most likely have huge advantages in the long run.

And you want as much of the index as possible in RAM. When the index is 10 times larger than necessary and do not fit in your RAM, you get a very expensive performance penalty!

You're absolutely right, but this is still a problem with JSON and XML. I have seen dates being represented in all kind of formats in the same document. Data cleansing has always been important when working with data in any format.

An example I currently have, Statistics Norway recently released version 2 of their API. You can now download about every data source they have. However they prefer that developers use JSON-Stat( https://json-stat.org/ ) inst

It performs as well as any other file system, but ZFS shines when you are IO bound as compression really helps when you do sequential scans. I have also tested ZFS with Microsoft SQL Server by exporting a ZVOL over iSCSI(FreeBSD) over 10G e

Add Groovy to that, and you have the dynamic typing and flexibility you see in Python and Ruby with Java. JDBC with Groovy SQL or JSON parsing with Groovy's JsonSlurper is a joy to work with.

I also have several big projects with hundreds of thousand lines of Groovy code that works fantastically well. And performance is top notch!

I save 2 billion rows of timeseries data every year. I use a regular btree index for "hot data" that is less than 6 months old and BRIN index for older data. You can do this by writing a functional index. You also have to spend so

by olavgg 10y ago
And Grails is very similar to Rails, and you get the full power of the JVM/Spring technology stack. And Groovy is a fantastic language that gives you the flexibility everyone like to dream about.

I'm currently learning C/C++ by just jumping into it, reading, trying, failing, (some swearing!) retrying and so on! It may not be the fastest or the most efficient path of learning, but at least I'm getting way better day by

This is seriously a big deal for the storage industry! Basically what you have created is something in high demand, yet lacking in the storage industry because of its complexity. What I've read so far is that this is a storage solution

This is cool! If you could make it possible to specify host, then it would possible to use this to upload directly to CephFS via Rados Gateway's S3 API.

No, I would not be using Photoshop, as I now dislike its user interface and find it hard and frustrating to use for simple tasks. But you know what! People are different and have different preferences. And I am far from alone preferring GIM
537.
by olavgg 11y ago
I think GIMP has a great user interface, it enables me to work fast, do things quickly, with high precision. And I am one of those who switched from Photoshop to Gimp. It is not because GIMP is better, but it has all the important features

by olavgg 11y ago
Well, you now have all features at your hand for development compared do Express. Though in many cases Express may be enough too. Anyway the license administration is the absolutely worst thing with SQL Server, which is a shame as it is rea

You will find FreeBSD inside every major internet giant, it is not used for everything but for corner issues where FreeBSD is better than for example Linux. There are many examples, one is that the Linux kernel VM system is not performing a

I've written CSS for over 10 years, and I don't use preprocessors at all. I've written small web pages, e-commerce sites, enterprise applications with tens of thousand users. And I find it really offending that you think this
