The questionably named Cloudera Navigator Optimizer

I only have mixed success at getting my clients to reach out to me for messaging advice when they’re introducing something new. Cloudera Navigator Optimizer, which is being announced along with Cloudera 5.5, is one of my failures in that respect; I heard about it for the first time Tuesday afternoon. I hate the name. I hate some of the slides I saw. But I do like one part of the messaging, namely the statement that this is about “refactoring” queries.

All messaging quibbles aside, I think the Cloudera Navigator Optimizer story is actually pretty interesting, and perhaps not just to users of SQL-on-Hadoop technologies such as Hive (which I guess I’d put in that category for simplicity) or Impala. As I understand Cloudera Navigator Optimizer:

CDH 5.5

I talked with Cloudera shortly ahead of today’s announcement of Cloudera 5.5. Much of what we talked about had something or other to do with SQL data management. Highlights include:

While I had Cloudera on the phone, I asked a few questions about Impala adoption, specifically focused on concurrency. There was mention of: Read more

Issues in enterprise application software

1. I think the next decade or so will see much more change in enterprise applications than the last one. Why? Because the unresolved issues are piling up, and something has to give. I intend this post to be a starting point for a lot of interesting discussions ahead.

2. The more technical issues I’m thinking of include:

We also always have the usual set of enterprise app business issues, including:

And perhaps the biggest issue of all, intertwined with most of the others, is:

Differentiation in business intelligence

Parts of the business intelligence differentiation story resemble the one I just posted for data management. After all:

That said, insofar as BI’s competitive issues resemble those of DBMS, they are those of DBMS-lite. For example:

And full-stack analytic systems — perhaps delivered via SaaS (Software as a Service) — can moot the BI/data management distinction anyway.

Of course, there are major differences between how DBMS and BI are differentiated. The biggest are in user experience. I’d say: Read more

Differentiation in data management

In the previous post I broke product differentiation into 6-8 overlapping categories, which may be abbreviated as:

and sometimes also issues in adoption and administration.

Now let’s use this framework to examine two market categories I cover — data management and, in separate post, business intelligence.

Applying this taxonomy to data management:

Cassandra and privacy requirements

For starters:

But when I made that connection and checked in accordingly with my client Patrick McFadin at DataStax, I discovered that I’d been a little confused about how multi-data-center Cassandra works. The basic idea holds water, but the details are not quite what I was envisioning.

The story starts:

In particular, a remote replication factor for Cassandra can = 0. When that happens, then you have data sitting in one geographical location that is absent from another geographical location; i.e., you can be in compliance with laws forbidding the export of certain data. To be clear (and this contradicts what I previously believed and hence also implied in this blog):

Basho and Riak

Basho was on my (very short) blacklist of companies with whom I refuse to speak, because they have lied about the contents of previous conversations. But Tony Falco et al. are long gone from the company. So when Basho’s new management team reached out, I took the meeting.

For starters:

Basho’s product line has gotten a bit confusing, but as best I understand things the story is:

Couchbase 4.0 and related subjects

I last wrote about Couchbase in November, 2012, around the time of Couchbase 2.0. One of the many new features I mentioned then was secondary indexing. Ravi Mayuram just checked in to tell me about Couchbase 4.0. One of the important new features he mentioned was what I think he said was Couchbase’s “first version” of secondary indexing. Obviously, I’m confused.

Now that you’re duly warned, let me remind you of aspects of Couchbase timeline.

Notes on privacy and surveillance, October 11, 2015

1. European Union data sovereignty laws have long had a “Safe Harbour” rule stating it was OK to ship data to the US. Per the case Maximilian Schrems v Data Protection Commissioner, this rule is now held to be invalid. Angst has ensued, and rightly so.

The core technical issues are roughly:

Facebook’s estimate of billions of dollars in added costs is not easy to refute.

Notes on packaged applications (including SaaS)

1. The rise of SAP (and later Siebel Systems) was greatly helped by Anderson Consulting, even before it was split off from the accounting firm and renamed as Accenture. My main contact in that group was Rob Kelley, but it’s possible that Brian Sommer was even more central to the industry-watching part of the operation. Brian is still around, and he just leveled a blast at the ERP* industry, which I encourage you to read. I agree with most of it.

*Enterprise Resource Planning

Brian’s argument, as I interpret it, boils down mainly to two points:

I’d add that SaaS (Software As A Service)/on-premises tensions aren’t helping incumbent vendors either.

But no article addresses all the subjects it ideally should, and I’d like to call out two omissions. First, what Brian said is in many cases applicable just to large and/or internet-first companies. Plenty of smaller, more traditional businesses could get by just fine with no more functionality than is in “Big ERP” today, if we stipulate that it should be:
