What are the performance differences between in-memory columnar databases
like SAP HANA and GridGain's In-Memory Database (IMDB) utilizing distributed
key-value storage? This questions comes up regularly in conversations with
our customers and the answer is not very obvious.
First off, let's clearly state that we are talking about storage model only
and its implications on performance for various use cases. It's important to
Storage model doesn't dictate of preclude a particular transactionality or
consistency guarantees; there are columnar databases that support ACID (HANA)
and those that don't (HBase); there are distributed key-value databases that
support ACID (GridGain) and those that don't (for example, Riak and
memcached). Storage model doesn't dictate specific query language; using
above examples - GridGain and HANA support SQL - HBa... (more)
The Facts and Fiction of In-Memory Computing
In the last year, conversations about In-Memory Computing (IMC) have become
more and more prevalent in enterprise IT circles, especially with
organizations feeling the pressure to process massive quantities of data at
the speed that is now being demanded by the Internet. The hype around IMC is
justified: tasks that once took hours to execute are streamlined down to
seconds by moving the computation and data from disk, directly to RAM.
Through this simple adjustment, analytics are happening in real-time, and
applications (as well as th... (more)
Why the Fast Data World Needs a Proven and Mature In-Memory Data Fabric
Much of what human beings experience as commonplace today - social
networking, online gaming, mobile and wearable computing -- was impossible a
decade ago. One thing is certain: we're going to see even more impressive
advances in the next few years. However, this will be the result of a
fundamental change in computing, as current methods have reached their limit
in terms of speed and volume. Traditional disk-based storage infrastructure
is far too slow to meet today's data demands for speed at volume, which ar... (more)
The State of Real-time Analytics in Financial Services
My company, GridGain, recently announced the results of a survey that asked
close to 200 IT decision-makers - including project managers, network
managers, software and business analysts, and other technology professionals
working in the financial services industry - about their companies'
attitudes, practices and challenges around data technology, with a focus on
the state of the industry's adoption of real time analytics technologies.
Here's what we found:

If you know anything about Hadoop architecture - the task seemed daunting to
us and it proved to be one of the most challenging engineering feat that we
have accomplished so far.
After almost 24 months of development, tens of thousands of lines of Java,
Scala and C++ code, multiple design iterations, several releases and dozens
of benchmarks later we have the product that can deliver real-time
performance to Hadoop with only minimal integration and no ETL required.
Backed-up by customer deployments that prove our performance claims and
validate our architecture.
Here's how we d... (more)
