NYT: Healthcare.gov Project Chaos Due Partly To Unorthodox Database Choice 334

First time accepted submitter conoviator writes "The NY Times has just published a piece providing more background on the healthcare.gov software project. One interesting aspect: 'Another sore point was the Medicare agency's decision to use database software, from a company called MarkLogic, that managed the data differently from systems by companies like IBM, Microsoft and Oracle. CGI officials argued that it would slow work because it was too unfamiliar. Government officials disagreed, and its configuration remains a serious problem.'" The story does not say that MarkLogic's software is bad in itself, only that the choice meant increased complexity on the project.

    There has got to be some reason that this DB that ive never even heard of (and i work with DBs, its not my main point of work but I know my way around DBs) got the gig over the more established players.

          For them, it is a wise choice. It brings job security using a non mainstream RDBMS, which means that the data would take man-years to be migrated to Oracle, DB/2, or even MS SQL server which may not have the horsepower of a SPARC or POWER7 box, but one can always partition and cluster the RDBMS. It also is expensive to keep maintained, so it provides additional job security, as the expertise for this architecture is rare.

      I used marklogic when I worked at a previous job and after learning how it worked and understanding it better, it made our jobs incredibly easy. It just had a serious learning curve.

      Marklogic is a nosql db, that uses XML for its object format and xquery for its query language. This thing is NOT mongodb. It actually works really well and allows for complex data modeling with the ability to do joins and have transactional isolation in making changes to the data as well as a really solid content processing framework with pipelining and all that jazz.

      Now, I can't imagine a reason for using marklogic, or any non-relational db for a project like this. The only clue is that marklogic has a lot of government contracts; mostly for the military. So maybe that's why it was used. But the fact that they chose a database system that they weren't experts in for a project that had so much visibility speaks volumes on how mismanaged this whole project was.

      • The only agencies that would need NoSQL type support are the ones spying on us. My take is that the insurance industry said they would only communicate in EDI-XML formats and somebody in management though that meant buying an XML-based system to be "compatible".

        To me, the fact that it was a major problem is an indicator of bigger problems. With systems like this, the database should be just a simple repository for persisting an retrieving domain models. If they want to do any non-trivial reporting on it the data should be replicated to a reporting repository. Treating the database a a simple persistence repository makes most database operations trivial, and better yet, decouples the database from the business, meaning that if you couldn't even manage the simple operations, replacing the layer is fairly trivial.

        The problem is when people think the database is the starting point for a system, not just a tool to be used to support what your business logic is doing. It sounds like that's what happened here.

        • I should add that with many languages and frameworks (Java & Spring/Hibernate for example), "we have machines for that". Only the fine tuning and performance tweaks need to be done my hand.

        Of course, by this criteria, a relational database is NOT "good".

      All actions by Federal government players seem rational when viewed from their point of view.

      The problem with most analysis, here or on other sites across the web, is in the assumptions. Specifically, if you assume that the government actions are for some benefit to the people, or efficiently completes some task (which is assumed to benefit the people), then nothing they do makes sense. That assumption makes for good outrage which can attract readers, but it doesn't answer the question of "why".

      When government actions are viewed in light of more obvious motivations, everything it does makes sense. You start to see them not as an pack of incompetent, bureaucratic screw-ups, but as a self-sustaining, self-absorbed, engine of corruption.

        Sad thing is, much of the behavior one sees out of federal contracts is due to taxpayer groups demanding anti-corruption measures. A great deal of the bureaucracy comes directly from people complaining about waste and demanding a complex audible process.

        I would actually put forward that the problem is not the government, our government is pathetically weak in many ways. The problem are all the private groups flexing their muscles and making the government dance. Most of the people I have worked with on these kinds of projects are good people who just want to get stuff done, but they are weighted down by a nearly impossible set of requirements, many of which are mutually exclusive, dropped on them by outside groups who mainly are interested in showing off their power to their own people and have no investment in the project itself being successful.... and often have an active interest in the project failing since they can always use that as fuel for more personal power.

Now MarkLogic, and NoSQL in general, will have a massive blow to their reputations, and it's unknown how badly this will hurt them.

There are scenarios where NoSQL systems are an ideal fit. However, NONE of those scenarios require data to be very reliably stored in a guaranteed and predictable way.

What you are losing with NoSQL real-time consistency horizontally across large number of instances spread over multiple data centres. When you are doing a transaction, and it should be "eventually consistent." meaning on the order of minutes. So if someone, somewhere else, who you do not know about and are not interacting with asks about your data, it might be a few minutes old. ACID makes it so that random person will get an upto the milli-second accurate answer. That makes transactions orders of magnitude slower, and much more complicated to scale. When you relax that constraint and let the people doing the transactions (the person, and the providers they are dealing with) get the right answer immediately, but just post the transaction so that the backups etc... get informed in due course, you gain much simpler scaling. The choice of NoSQL vs. SQL is not about the importance of the transaction. It is about application scaling and design, and the biases (tastes?) of the team doing the work.

      I ran into this recently at a company whose new head of engineering was talking to me (an outsider) about the technology problem they had to solve and I thought it sounded very traditional and simple except they'd need to carefully plan for horizontal scaling.

      Basically a potentially huge number of devices (in the range of millions) would be reporting in periodic data that had to be stored and potentially evaluated in real-time. The data was quite easily swim laned by geolocation and the data had no appreciable inter-related significance. So basically, one piece of data from one device had nothing to do with any other device's information except in the general sense that can come from a more heuristic correlation of their data.

      I should mention that the new engineering head and I had already (together) handle a situation very similar to this at a previously successful software company.

      Well, the new engineering head had inherited an external architect who had different ideas. All of these different ideas involved things like Cassandra over Hadoop, AMP/Spark, BDAS. He showed me a diagram of the technologies he wanted to integrate and I'd never heard of almost half of them (and I deal with scaling issues all the time), this diagram had about 15 different technologies stacked together. It was crazy - all to solve a relatively simple data volume problem.

      Almost needless to say, I advised otherwise, and afaik they're going the bid data way because it will make it easier for them to pull in VC money since shockingly few VC's actually evaluate technology before they put money in (I do this for VCs also, and other VCs wonder how I get paid to do this, lol.)

    "Some people, when confronted with a problem, think 'I know, I'll use XML.' Now they have two problems."

    MarkLogic is an XML database, not a relational database, so if your data primarily consists of XML content then it's the right tool for the job. Sounds like the vendor building the system had a favorite hammer and decided that a rather traditional database problem looked like a nail.

    MarkLogic itself is fine if your data fits neatly into an XML schema, but with healthcare.gov that tree is probably enormous and hard to optimize for DB activity.

      Sounds like the vendor building the system had a favorite hammer and decided that a rather traditional database problem looked like a nail.

      It was the Medicare folks that imposed MarkLogic over the objections of the prime contractor. Calling Medicare a "vendor" is a bit of a stretch. Like non-IT staff calling themselves "customers" of IT in a corporation, as if they have a choice of IT departments.

      Another sore point was the Medicare agency’s decision to use database software, from a company called MarkLogic, that managed the data differently from systems by companies like IBM, Microsoft and Oracle. CGI officials argued that it would slow work because it was too unfamiliar. Government officials disagreed, and its configuration remains a serious problem.

      The CGI argument was that it would slow work. I have absolutely no doubt about that. Every NoSQL system is it's own distinct thing with unique APIs, protocols, conventions, quirks, etc. This is fine when you are dealing with a limited group of good developers that can be expected to rapidly climb a learning curve. This is not fine when you are the top contractor in a herd of contractors, populated by a vast number of mediocre programmers that last learned anything new in the late 90's.

      In that case the correct choice is to select the most ubiquitous technologies. A boutique NoSQL XML-base is not appropriate, even if it is excellent, which MarkLogic may be. I don't know. I just know CGI was 100% correct in objecting to it. CGI's fault in this case was its failure to win that argument.

      Not that it matters much. The project was doomed in any case — political agenda driving pie-in-the-sky requirements using crony contracting — Fucked at birth, as they say.

  • Well they did have the flashiest ads which used lots of buzzwords.

    Why not just use MySQL, MongoDB or MariaDB? At least use a database system that has good support, an easy learning curve and loads of followers. That beings said, proper testing would easily of mitigated this entire issue.

    I worked as a contractor developing a system at FDA. It lasted for 5 years. Inside the Beltway, it's pretty much the same all over. Dysfunctional communications and ridiculous breakdown of authority not corresponding to lines of management. No accountability. Project management requirements that have never been followed by any project. No commitment to the output of requirements gathering. No requirements change control. No performance engineering. Inadequate testing. No acceptance process by the government. IT groups with oversight for contractor output that have never written a line of code. All in all, pretty sick and ugly. Prior to my project there were 5 failed attempts. My project followed PMI practices, worked them hard and succeeded.

    From the summary:

    "The story does not say that MarkLogic's software is bad in itself, only that the choice meant increased complexity on the project."

    Unless that complexity was necessary to solve a problem, then it is in fact bad.

    It is NEVER the tool, but who and why it was chosen.

    Furthermore, MarkLogic is a legitimate NoSQL vendor with strong ACID.

    So the question is "how does MarLogic screw up the site", without the answer to that question, we should all refrain from pointing finger to merely a small piece in a huge software project.

    NoSQL is NOT the new hotness, it's been out there for at least 5 years and many successful projects are using them, so for the ones that things NOSQL shouldn't be used, wake up and breath some fresh air.

  • So the private-owned company has "officials". Cool...
  • I get there must be tons of complexity in managing healthcare.gov site interacting with all necessary stakeholders... Must be quite a lot of different databases, systems, operators to say nothing of complexity of working the actual problem space. I can understand how there might be glitches that cause wrong rates and plans to be communicated.

    What I am still puzzled by are the "waiting rooms" with 40k people waiting to use a site. What the hell can justify it being so computationally expensive to spit out

    I've used it, personally, to implement a public-facing website. That site endured the dreaded 'slashdot effect' several times. No failures.

    When implemented properly, Marklogic is damn near unkillable. It will slow down, it will reject connections when queues are full, but it will not fall over. Naturally, this assumes proper underpinnings and capacity calculations. With Marklogic, those are actually documented.

    Mandatory disclosure: I do not have and have never had any association with Marklogic other than a paying customer.

Do not simplify the design of a program if a way can be found to make it complex and wonderful.

Working...
