mapleFU opened a new issue, #39377: URL: https://github.com/apache/arrow/issues/39377
### Describe the enhancement requested in `::arrow::io::CompressedInputStream::Impl`, the `decompressed_buffer_` is initialized as 1MB, and would: 1. Call `Resize` to release the memory if possible ( https://github.com/apache/arrow/blob/main/cpp/src/arrow/io/compressed.cc#L303 ) 2. Droped the memory when buffer exhausted ( https://github.com/apache/arrow/blob/main/cpp/src/arrow/io/compressed.cc#L324 ) Can we avoid re-allocating the buffer frequently, trying to keep 1MB data here? ### Component(s) C++ -- This is an automated message from the Apache Git Service.
