Hi

[e.geschwinde]

I want to introduce myself.

I'm coming fomr the company www.cybertec.at

As you can see we are a postgresql centric company.

So I'm interested in this project


I have a few questions about your replication server.

is it based on J2EE technology and does it need an app server?

Hi Ewald,

It is not based on any J2EE technology and it doesn't need any app server.

------

Last week, we put on-line some "toys" that show how to use the the
PostgreSQL/G.

On next Monday, we will be releasing a replication engine that could be
be used and easily extended to implement a variety of replication protocols.
In its first version, it will come with a primary backup replication
protocol(synchronous and asynchronous)
and a database state machine.

We would like to here your suggestions and opinion on our project.


Best regards,

Alfranio Junior.

Thanks - we try to do our best and if we can we contribute to the
project - maybe put more workforce in it.

One question can you add nodes to the cluster or can you make catchup of
some nodes?

Yes. The replication engine use on-line recovery and synchronize
recovery with normal processing.
Currently we use the PostgreSQL tools for this purpose, pg_dump and
pg_restore.
We are working on other recovery protocols that just transfer the missed
updates.

thanks for the info we have implemented a multimaster in java for pg one
year ago - but it was too slow
and we have solved the problem for this missed updates with an
in-memory  queue.

When is the expected release of the rep server - I'm hungry for testing ;)
