Both Custom Dimensions and Flow Tags allow you to label flow records based on criteria defined in advance and evaluated at ingest. As announced in the HSCD topic of our May/June 2018 Product Update, our backend engineering team has been hard at work re-engineering these systems under the hood to drastically increase their capacity, scalability, and agility. As of September, all Custom Dimensions natively support this increased scale.

As part of enhancing the usability of Custom Dimensions and Flow Tags, we’ve also added a new Batch API that simplifies management by enabling bulk loading of either Populators (for Custom Dimensions) or Tags. To help you get started, we’ve posted a Hypertagging API in GitHub that you can use in Python to call our Batch API. For additional information, please refer to the Batch API topic in the Knowledge Base or contact the Kentik Customer Success team at support@kentik.com.
