Even more goodies are coming in RavenDB 3.0. Below you can see how to visualize the replication topology in a RavenDB Cluster. You can also see that the t5 database is down (marked as red). This is important, since this gives us the ability to check the status of the topology from the point of view of the actual nodes. So a node might be up for one server, but not for the other, and this will show up here. Beside, it is a cool graphic that you can use in your system documentation and it is...

A customer asks in the mailing list: Due to data protection requirements, we have to store a users data closest to where they signed up. For example if I sign up and I’m in London, my data should be stored in the EU. Given this, how do we ensure when replicating (we will have level 4 redundancy eventually), that any data originally written to a node within say the EU does not get replicated to a node in the states? The answer here is to use to features of RavenDB together. Sharding and...

We got a customer question about a map/reduce index that produced the wrong results. The problem was a problem between the conceptual model and the actual model of how Map/Reduce actually works. Let us take the following silly example. We want to find all the animal owner’s that have more than a single animal. We define an index like so: // map from a in docs.Animals select new { a.Owner, Names = new[]{a.Name} } // reduce from r in results group r by r.Owner into g where...

Yes, I talked about this already, but we made some additional improvements that make it even cooler. Here is a document: And here is the index: Now, let us look at what happens when we go to the map/reduce visualizer: This is a highly zoomed out picture, let us zoom a little (click it for higher zoom): As you can see, we can see all the documents that have any reduce keys shared with the reduce keys from the document we started from. That is going to make explaining, and debugging,...

Yes, I choose the title on purpose. The topic of this post is this issue. In RavenDB, we use replication to ensure high availability and load balancing. We have been using that for the past five years now, and in general, it has been great, robust and absolutely amazing when you need it. But like all software, it can run into interesting scenarios. In this case, we had three nodes, call them A, B and C. In the beginning, we had just A & B and node A was the master node, for which all the data...

This can be a very short post, just: See CAP. Unfortunately, we have a lot of people who actually have experience in using distributed transactions, and have a good reason to believe that they work. The answer is that yes, they do, as long as you don’t run into some of the interesting edge cases. By the way, that is not a new observation, see The Two Generals. Allow me to demonstrate. Assume that we have a distributed system with the following actors: This is a fairly typical setup. You have...

I have an interesting situation that I am not sure how to resolve. We need to record the last request time for a RavenDB database. Now, this last request time is mostly used to show the user, and to decide when a database is idle, and can be shut down. As such, it doesn’t have to be really accurate ( a skew of even a few seconds is just fine ). However, under load, there are many requests coming in (in the case presented to us, 4,000 concurrent requests), and they all need to update the last...

In my previous post, I did some rough “benchmarks” to see how message passing options behave. I got some great comments, and I thought I’ll expand on that. The baseline for this was a blocking queue, and we managed to process using that we managed to get: 145,271,000 msgs in 00:00:10.4597977 for 13,888,510 ops/sec And the async BufferBlock, using which we got: 43,268,149 msgs in 00:00:10 for 4,326,815 ops/sec. Using LMAX Disruptor we got a disappointing: 29,791,996 msgs in 00:00:10.0003334...

I’m designing a new component, and I want to reduce the amount of complexity involved in dealing with it. This is a networked component, and after designing several such, I wanted to remove one area of complexity, which is the use of explicitly concurrent code. Because of that, I decided to go with the following architecture:   The network code is just reading messages from the network, and putting them in an in memory queue. Then we have a single threaded event loop that simply goes over the...
