…metry#43574) <!--Ex. Fixing a bug - Describe the bug and how this fixes the issue. Ex. Adding a feature - Explain what this achieves.--> #### Description The sumo_ic marshaler was incorrectly blocked from using compression. Sumo Logic's Installed Collector compresses archive files before S3 upload, but the OpenTelemetry exporter prevented this, causing format incompatibility. Root cause: The exporter used ContentEncoding: "gzip" for all compressed uploads, which signals HTTP transfer compression (auto-decompressed by AWS). Archive formats like sumo_ic need files to stay compressed permanently. Solution: Added isArchiveFormat flag to distinguish between archive formats (files stay compressed) and transfer formats (HTTP optimization). The flag controls whether ContentEncoding header is set during upload. <!--Describe what testing was performed and which tests were added.--> #### Testing - Manual testing: Downloaded files from S3, verified gzip compression with file and gunzip commands - Unit test passed: ``` ➜ awss3exporter git:(sumoCompression) ✗ make test /Users/timothy.chan/Desktop/opentelemetry-collector-contrib/.tools/gotestsum --rerun-fails=1 --packages="./..." -- -race -timeout 900s -parallel 4 --tags="" ∅ internal/metadata ✓ internal/upload (cached) ✓ . (2.662s) DONE 98 tests in 2.662s ``` <!--Describe the documentation added.--> #### Documentation - Removed outdated README that gzip doesn't support sumo_ic marshaler <!--Please delete paragraphs that you did not use before submitting.-->
