The service does a look-up against HBase. As mentioned before, it leverages multiple data sources from different providers, which we load into memory upon deployment. Average response time is 10–20 millisecond for each request, decodes to one trim 93% of the time, and can handle up to 15,000 requests per second. UVD is currently the most heavily used API throughout the company. Lots of work has been done to make UVD, the TrueCar VIN decoding service, operate the way it does today. If build data information is not available, we end the VIN decoding process and calculate the VIN decoding confidence score.īased on this understanding of the challenges, importance, business use cases, and details of our VIN decoding process, we will now dive into the technical details of our one and only VIN decoder in TrueCar.
