- Remove context attribute from LogRecord to prevent memory inflation. - Update signature to accept context separately. - Update and SDK processors to align with the new signature. - Update tests to reflect the breaking changes. This aligns the Python SDK with the OpenTelemetry specification and resolves memory usage concerns in BatchLogRecordProcessor.

There was a problem hiding this comment.
I think removing the full context is fine, but we might want to keep at least SpanContext.

LogRecordProcessor.on_emitsignature to accept context separately.Logger.emitand SDK processors to align with the new signature.This aligns the Python SDK with the OpenTelemetry specification and resolves memory usage concerns in BatchLogRecordProcessor.
Description
This PR implements the architectural changes discussed in #4977 to address memory usage issues in LogRecord. Storing the full
Contexton each LogRecord caused significant memory overhead because theContextcould not be GC'd until the log was exported.By removing context from LogRecord and passing it as a separate argument to
LogRecordProcessor.on_emit, we resolve the memory inflation while maintaining consistency with other OpenTelemetry SDKs (Go, JS) and the specification.Fixes #4957
Type of change
How Has This Been Tested?
I have updated the SDK's log test suite to reflect the new signatures and verified that all tests pass.
pytest opentelemetry-sdk/tests/logs/78 passed, 39 warnings, 2 subtests passed in 2.56sDoes This PR Require a Contrib Repo Change?
