Reducing Log Volume with the OpenTelemetry Log Deduplication Processor

The OpenTelemetry Log Deduplication Processor significantly reduces log volume by aggregating identical log messages over a configurable time window, replacing numerous duplicates with a single entry detailing the frequency of the event. This is achieved by hashing log attributes (excluding timestamps) and emitting a log with a `logcount`, `firstobservedtimestamp`, and `lastobserved_timestamp` when the interval expires – preserving crucial information without storing redundancy. While introducing a slight latency equal to the configured interval, this processor offers a valuable tradeoff for reducing storage costs and improving signal clarity in high-volume logging systems.
