You can use it to monitor applications and troubleshoot issues. Uptrace is an open source APM open in new window for OpenTelemetry that supports distributed tracing, metrics, and logs. It enables efficient data collection, processing, and export to improve observability, troubleshooting, and performance of software systems. OpenTelemetry Collector open in new window is a valuable component for monitoring applications and infrastructure in distributed environments. To monitor PostgreSQL open in new window, you can use OpenTelemetry PostgreSQL open in new window receiver that comes with OpenTelemetry Collector. UUID `bun:"type:uuid"` } # Monitoring performance UUID `bun:",pk,type:uuid,default:uuid_generate_v4()"`ĪuthorUUID uuid. Such identifiers are proven to be unique, but are larger and slightly slower than 64-bit sequential numbers. Usually, UUIDs are generated by taking 16 random bytes and the uniqueness is based on the sheer quantity, not the generation algorithm. You can use UUIDs when you need to generate a globally unique indentifier without using an id generation service, for example, OpenTelemetry open in new window uses 16-bytes identifiers as a trace id. This makes UUIDs particularly useful in scenarios where there is a need to uniquely identify objects, entities, or resources in distributed systems, databases, or other applications. The purpose of UUIDs is to provide a way to generate identifiers that are highly unlikely to collide with other identifiers, even if they are created on different systems or at different times. UUIDs are often represented as a string of 36 characters, typically in a format such as "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where each "x" represents a hexadecimal digit. It is a 128-bit identifier used to uniquely identify information in computer systems and applications. UUID stands for Universally Unique Identifier. In PostgreSQL, you can generate UUIDs using the uuid_generate_v4 function from the uuid-ossp extension. View on GitHub # PostgreSQL: Generating UUID primary keysĪ universally unique identifier (UUID) is a 128-bit number that is generated in a way that makes it very unlikely that the same identifier will be generated by anyone else in the known universe (globally unique).
