Using VoltDB to Get JPMML into Production

In the previous articles, Getting Machine Learning into Production and Using VoltDB to Get H20 into Production, I discussed the broad problems you face when you try to commercialize machine learning and showed how to integrate h2o. In this article I’ll show how you can use PMML inside VoltDB. There are two ways to use [...]

Getting Machine Learning Into Production With VoltDB

Congratulations! You’ve mastered machine learning and can now generate a model that will help your enterprise succeed. There’s just one problem. Or rather several, actually. Below we discuss the challenges you face getting an ML model into production and how VoltDB can help. For the purposes of this article let’s assume that your model’s job [...]

v8.2 Released

This week, we released VoltDB v8.2. Here are some of the highlights: Table TTL If you’ve ever built a high-volume app for Volt, or hooked Volt up to a Kafka or Kinesis stream, you know how important it is to age out the old data so that you don’t overflow memory. In the past, you [...]

VoltDB v8.1 Released

We are pleased to announce VoltDB v8.1. This release includes features that can reduce the total cost of ownership of your VoltDB solution, with improvements to memory management of replicated tables, and performance improvements for many applications. These features include: Reduced Memory for Replicated Tables Replicated (i.e. non-partitioned) tables are now stored only once per [...]

How VoltDB Serves Machine Learning Models in Real-Time

In my previous blog on big data analytics, we discussed how to apply your big data analytics to real-time applications. The idea is that, if you have built analytics on your data, the next step is to use the analytics directly in the applications to automate your business workflow and remove the manual components. In this […]

VoltDB Releases V8

VoltDB is pleased to announce V8. Our engineering team has spent the last year adding features across the product to bring you the fastest database to handle millions of decisions per second, with single-digit millisecond latencies. VoltDB’s customers use this power to solve real business problems that require prectibable low latency, often at very large […]

VoltDB Bonded Network Compatibility

In this post we describe VoltDB’s high availability architecture and how it interacts with bonded networks. Together they offer protection and continuity against network failovers. How do we know? Because we tested it and describe the tests we ran to verify compatibility with various bonded network modes. What Is a Bonded Network? Bonded networking is […]

Key Considerations for a Modern Database to Operate at Scale

Modern applications have two primary needs: performance and ease of operations, both at scale. Performance The performance consists of two aspects: throughput and latency. Both are driven by applications becoming machine-driven i.e. API-driven. Humans will wait much longer than an API will since APIs have strict latency expectations due to timeouts. When you take a […]

Questions and Answers about Modern Database Architecture

VoltDB and DBTA teamed up to host a webinar in October titled “Architectural Considerations for a Modern Database to Operate at Scale”. We had a number excellent questions during that session, which are reproduced below. For those who missed the webinar, you may view it here in its entirety. Editor’s Note Unless otherwise noted, the […]

Using UDF for Machine Learning

We added support for scalar user-defined functions in our recent release, VoltDB V7.6. With this feature, users can write their own SQL functions in Java and load them into VoltDB. Those functions, once loaded, can be used in all kinds of SQL queries just like any other built-in SQL functions. User-defined functions can give you […]
