Highlight.io emphasizes its commitment to using open source software, particularly OpenTelemetry, to manage its infrastructure and efficiently process substantial amounts of customer data. The adoption of OpenTelemetry across all language SDKs ensures a consistent standard for data ingestion, simplifying data export for customers already familiar with the tool, and enabling a gradual adoption for those who are not. OpenTelemetry's efficient data transfer is facilitated through batching, compression, and a hosted collector, which eliminates the need for additional software installations and streamlines integration with applications. Additionally, the tool allows developers to report custom data through trace events, providing deeper insights into application performance by using attributes such as exception type, message, and stacktrace. Highlight.io also expresses its commitment to contributing to the open source community, recognizing OpenTelemetry as a vital tool in modern software development.
