Could you describe where your system sits on the FIT spectrum that the article discusses? Do you believe that scheme for thinking about the trade-offs between isolation, throughput, and fairness doesn't hold for marklogic?

They absolutely apply to MarkLogic. We absolutely prioritize FI over T. Coordinating transactions, along with journaling, security and many other features costs in terms of throughput. Now, that cost is relative - our ingest rates are still very quick and we linearly scale. That said, copying JSON or XML into a distributed file system is way quicker.

I'm not sure the buckets provide much guidance in real life. One can configure a system, for an insert only batch load, to prioritize T without giving up FI for the data and transactions that aren't part of that load. If an FI system can load faster than an IT system, this distinction ends up not actually mattering. Plenty of folks who need FI are using products that don't provide it because of culture + budget.
