Based on the information you've provided, it seems like the issue is related to handling GZIP compressed requests. Here are some potential solutions and insights:
Ensure Proper GZIP Handling: The server should properly decompress the request body before processing it and recompress the response if necessary. This might involve wrapping the request input stream in a GZIPInputStream
for decompression and similarly using a GZIPOutputStream
for response compression.
Stream Resetting: If the bug involves changes to the request stream that prevent it from being read again, consider using a mechanism to buffer the input stream so it can be read multiple times. This could involve copying the input stream to a ByteArrayInputStream
that supports resetting and can be read multiple times without losing the data.
Optimize Compression and Decompression: Review the compression and decompression logic for efficiency. Depending on the data characteristics, you might optimize these operations by adjusting the buffer size or using different compression levels.
Concurrency and Resource Management: Ensure that the compression and decompression operations do not become bottlenecks under high load. This might involve profiling the server under load to identify hotspots and optimizing or parallelizing operations where possible. Additionally, ensure that resources like Deflater
and Inflater
instances are properly managed and released after use to avoid memory leaks.
Error Handling and Logging: Improve error handling and logging around the compression and decompression operations. Specifically, ensure that any exceptions thrown during these operations are logged with sufficient detail to diagnose issues. This might help in identifying and resolving the root cause of the server slow log issue.
Review Client-Side Implementation: If the issue is related to how the loader sends GZIP compressed requests, review the client-side implementation to ensure it correctly sets the Content-Encoding: gzip
header and properly compresses the request body. Misconfiguration or bugs on the client side could lead to issues on the server.
Server Configuration: Check the server configuration for settings related to request body size limits, timeout settings, and compression. It's possible that server configuration might need adjustment to better handle large or compressed requests.
Without specific details on how the server handles incoming requests and integrates with GZipUtil
, these are general insights and potential solutions. Further investigation and debugging would be necessary to pinpoint the exact cause of the issue and implement the most appropriate solution.
For more details, you can refer to the source code of the GZipUtil
class and the DecompressInterceptor
class in the Apache HugeGraph repository:
I hope this helps! If you have any further questions or need more clarification, feel free to ask.

Expected & Actual behavior (期望与实际表现)
we support slow log before ,but it cause bug when loader batch import data, the feat PR see https://github.com/apache/incubator-hugegraph/pull/2327
and later we downgrade it ,see pr : https://github.com/apache/incubator-hugegraph/pull/2347
the bug due to:
we need get post body from req, and we need set it back to request, so it changed. the loader request use the "GZIP" header, after get post body, server cant read it so we ready to resolve it , use BufferedInputStream to cache the stream:
` BufferedInputStream bufferedStream = new BufferedInputStream(context.getEntityStream());
