Module attrs 

Helpers for OTel attribute / AnyValue → JSONB translation Converts OTel KeyValue arrays + scalar AnyValue instances to JSONB bytes.

Mapping follows the plan’s “Attribute value encoding” table:

• string → JSON string
• int / double / bool → JSON number / bool
• bytes → base64-encoded string (existing properties consumers expect text)
• array / kvlist → recursive JSON

The output is a JSONB-encoded {key → value} blob suitable for the properties columns across log_entries, measures, and otel_spans.

Functions

any_value_to_jsonb

Converts an AnyValue to a jsonb::Value. Recursively handles arrays and kvlists.

any_value_to_string

Renders AnyValue to a flat string for fields that need a textual form (e.g., the msg column when an OTel log body is structured).

attrs_to_jsonb

Serializes a flat (key → value) map (with optional extra entries layered on top) to JSONB bytes. Output ordering is alphabetical, matching serialize_properties_to_jsonb.

scope_extras

Builds the per-row otel.scope.* properties (name, version, attr.*, schema_url) that ride alongside row attributes in the JSONB properties column. Skips empty fields so absent scopes don’t pollute the output.

severity_number_to_level

Maps OTel severity_number (1–24) to micromegas Level (1–6).

to_jsonb_bytes

Encodes a JsonbValue to its on-wire JSONB bytes.
