feat: use default stream name if header missing in ingestion by nikhilsinhaparseable · Pull Request #1837 · parseablehq/parseable

nikhilsinhaparseable · 2026-10-29T05:10:14Z

x-p-stream no longer requires to be mandatory header if found in header, use that for ingestion
else, use default stream name

arbitrary logs - default_logs
otel logs - default_otel_logs
otel traces - default_otel_traces
otel metrics - default_otel_metrics

with this change, otel collector config simplifies as one exporter config works instead of config for each telemetry type

Summary by CodeRabbit

New Features
- Ingestion requests can now omit the stream name; a suitable default is selected based on the request path or telemetry type.
- Requests without a stream name can use the path-derived default for authorization.
Bug Fixes
- Invalid stream-name headers are handled consistently. Kinesis requests with a valid authorization header can proceed without a stream-name header.

Walkthrough

Ingestion handlers now use default stream names when X-P-Stream is absent. Middleware accepts optional stream headers and uses request paths to select defaults for ingestion authorization.

Changes

Stream Defaults and Header Handling

Layer / File(s)	Summary
Stream default selection `src/handlers/mod.rs`	Adds default stream names, a helper to parse the stream header with a fallback, and path-based default selection.
Optional stream headers in middleware `src/handlers/http/middleware.rs`	Kinesis extraction accepts a missing stream header. Ingestion authorization uses a path-derived default when the header is unavailable or invalid. Tests cover missing and supplied stream names.
Stream resolution in ingestion handlers `src/handlers/http/ingest.rs`	Log ingestion uses the general default when the stream header is absent. OTEL ingestion selects a default based on the log source.

Reject invalid Kinesis stream attributes before JSON fallback.

When X-P-Stream cannot be converted to an HTTP header, extract_kinesis_headers returns before inserting LOG_SOURCE_KEY. With valid independent authorization, the request then uses default_logs and LogSource::Json. The valid Kinesis envelope can be stored as one ordinary JSON record, so records[*].data is not base64-decoded into Kinesis records.

Return and propagate a header error instead of silently returning.

Suggested fix

// Extract Kinesis Firehose headers if applicable if self.action.eq(&Action::Ingest) { - extract_kinesis_headers(&mut req); + if let Err(error) = extract_kinesis_headers(&mut req) { + return Box::pin(async move { Err(error) }); + } } ... -fn extract_kinesis_headers(req: &mut ServiceRequest) { +fn extract_kinesis_headers(req: &mut ServiceRequest) -> Result<(), Error> { ... - Err(_) => return, + Err(_) => { + return Err(Error::from(PostError::Header( + crate::utils::header_parsing::ParseHeaderError::InvalidValue, + ))); + } ... req.headers_mut().insert( HeaderName::from_static(LOG_SOURCE_KEY), header::HeaderValue::from_static(LOG_SOURCE_KINESIS), ); } + Ok(()) }
