Highlighting features in this release

1. Log Marker and Log records

• Log indicator markers on span for quick analysis
• Log records at the trace level

2. Raw Span Grouper Optimizations

Problem

could not increase maxSpanCount beyond 50, leading to large amount of span drops, huge cpu throttling observed on high span count

Reason:

• Fetch complete trace on every incoming span, leading quadratic time complexity for serde thus high cpu usage
• rocksdb better performant with smaller size records
• As the trace grows in size, high chance of blob exceeding kafka message size, and lots of cpu cycles wasted on retries for publishing message

Approaches

• Store spans in a state store and stitch trace at punctuate
• Store chunk of span in a span state store, stitching of trace same as previous
