Struct StreamMetadata

pub struct StreamMetadata {
    pub process_id: Uuid,
    pub stream_id: Uuid,

Expand description

Analytics-optimized stream metadata.

This struct is designed for analytics use cases where stream properties need to be efficiently serialized to JSONB format multiple times. Unlike StreamInfo, which uses HashMap<String, String> for properties, this struct stores pre-serialized JSONB data to eliminate redundant serialization overhead.
