[derek-ho]

Is your feature request related to a problem?
Support Fluent bit in trace analytics and app analytics

What solution would you like?
We need to align on a schema to add support for fluent bit trace data

1. Overview of Fluent Bit + OTEL Tracing

• Does Fluent Bit follow OTEL/OTLP?
• Opensearch Exporter for OTEL collector - timeline?

2. OTEL Tracing and OpenSearch today (Jaegar / Data Prepper)

• Heavily schemtized
• Will need to Add a new schema to support OTEL/OSS/

3. Fluent Bit OpenSearch plugin requirements (OTEL → JSON or alternative)

• Why does this mean? OTEL exporter?
