So far, we haven't had any particular need for native support for parquet files. This type of import can be done satisfactorily via RayPy, and there is also a plugin that allows you to access kdb+ instances.

Here's a new kdb+ like time-series database and programming language. This new implementation is being tried to avoid well known kdb+ drawbacks (including its famous price tag) and to add many new features now missed by many kdb+ progr

every instance can export its monitoring information as 9p virtual filesystem, which easily can be mounted from outside we debug server code in BEAM, Erlang on Xen is a deployment platform, if instance crashed we simply restart it. intruder

BEAM ("official" Erlang VM) starts much longer. Erlang On Xen has it's own VM (written from scratch), it was designed for run without OS and to srtart very fast, particularly.

When you sat in container, you're limited with libraries of host OS, and there still will be some issues with migration and resource management (on large scales)

Sorry gentlemen, we had used libvirt and it set some limits. http://erlangonxen.org/blog/glimpse-truly-elastic

yes, very soon we will start to give attention to writing application over this platform. there is some work still needs to be done in management stack, but it's manageable amount of work.

Thanks. We used libvirt for this demo, unfortunately it sets its own limits.

I'm afraid, only few people are familiar with internals of Erlang VM, especially, if that VM is totally different from BEAM. Thus, there's no reason to opensource it, at least yet. Though, build.erlangonxen.org is open, contains the most re

Current implementation runs in Xen PV domain and uses Xen's hypercalls. There are no strong dependencies, though, Ling easily can be ported for other hypervisors. Xen is the priority, since it's the plaform for all major public clouds.

Zerg is just a demo that shows how elastic and scalable could be OSless VMs even over current cloud infrastructure

by viktorsovietov 14y ago
libvirt is the limit in this case...

Scalable MapReduce, for example, super scalable web servers tolerant for any possible spikes of load, including abuse-resistant hostings, personal virtual appliances... there are many possible usecases, indeed

Sorry, gents, we don't have real datacenter there, just a single host, and libvirt sets its own limitations.

Actually, we didn't modify Ericsson's Erlang VM, we have written our own.

Right, it's just example, right, it dies after each request - you can check the code on github. Also, you can review the detailed structure of time spending on the second half of zerg's page.
