# Summary [NIFI-15888](https://issues.apache.org/jira/browse/NIFI-15888) Adds an internal size limit of 10 MB to the Standard Content Viewer, avoiding attempts to load, format, and render large FlowFiles. The internal limit of 10 MB aligns with a previous comment on Apache Avro formatting, which actually limited to the output size to 2 MB. The implementation uses the `LimitingInputStream` to avoid reading more than 10 MB from the referenced FlowFile. The limit applies to both formatted and unformatted responses. Unformatted responses with content exceeding the limit return an `HTTP 206` status indicating Partial Content returned. Formatted may throw an exception when the limit does not align with expected structural boundaries. In this case, the server returns an HTTP 500 with message indicating length exceeds maximum. As a best effort viewer, returning an error avoids both server and client memory consumption concerns. The hexadecimal viewer continues to provide a general way to view initial bytes. Additional unit tests exercise length limiting behavior with formatted and unformatted responses. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` - Pull request contains [commits signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) with a registered key indicating `Verified` status ### Pull Request Formatting - Pull Request based on current revision of the `main` branch - Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `./mvnw clean install -P contrib-check` - [X] JDK 21 - [X] JDK 25 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
