Shard-Query blog

The only open source MPP database engine for MySQL

A new blog for Shard-Query

Instead of posting things about Shard-Query on my personal blog, I decided to get a dedicated space on the web for blogging about Shard-Query.

Oh, and Shard-Query 2.0 beta 1 is out today:
http://code.google.com/p/shard-query

I’ll do a blog post with a quick overview of the new features and changes soon.

    What happens while querying if one of the shard goes down due to n/w issue or disk failure or any machine issue ?
    Would query still return with partial results or is it fail saying one of the shard is down?
