Adapting TPC-C for MongoDB - reviewing a VLDB paper

This is a review of Adapting TPC-C Benchmark to Measure Performance of Multi-Document Transactions in MongoDB which was published in VLDB 2019. I appreciate that MongoDB and Asya Kamsky took the time to get this published. That can be a weekend and nights project when in industry. I also appreciate that this not a benchmarketing effort. The purpose wasn't to overstate performance. The purpose was to show how to get good performance on a TPC-C like workload with MongoDB and realistic hardware and configurations. I hope for a similar effort on MongoDB with Linkbench.

My comments:

  • Work was done to reduce write-write conflicts which will be more likely given the extra commit latency from using w:majority writeConcern on a 3-node cluster. That …

Open Core Summit and OSS glue code

I am optimistic about the Open Core Summit. It can be something that benefits users, startups, the source-available community and the OSS crowd. The summit has many of the important people from the open core community. It is an opportunity for them to collaborate -- form a foundation, reduce open core license proliferation, discuss the next license to be reviewed by OSI and most importantly -- fix the open core marketing approach.

I appreciate that startups put so much time and money into building interesting system software that is shared either as OSS or source-available. I haven't enjoyed much of the marketing about the challenges that cloud creates for VC-funded …
