## Description of change This PR implements a new PhysicalIO design with key improvements: **Fixed Block Size:** Previously, block sizes varied based on request ranges, requiring entire request ranges to complete before blocks became available. The new design uses fixed-size blocks that become ready as soon as individual blocks are filled, enabling faster data access and better parallelization. **Direct Block Writing:** Eliminates an extra memory copy by writing S3 data directly into Block storage instead of copying from intermediate buffers, reducing memory overhead and CPU usage. **Improved Concurrency:** Fixed-size blocks allow multiple blocks to be processed independently, improving throughput for concurrent read operations. **Better Memory Management:** Predictable block sizes enable more efficient memory allocation and cache management strategies. **Enhanced Read Performance:** Blocks become available for reading as soon as they're filled, rather than waiting for entire request ranges to complete, reducing read latency. #### Relevant issues #286 #287 #288 #289 #294 #316 #320 #323 #324 #### Does this contribution introduce any breaking changes to the existing APIs or behaviors? No #### Does this contribution introduce any new public APIs or behaviors? No #### How was the contribution tested? Unit tests, microbenchmarks #### Does this contribution need a changelog entry? - [ ] I have updated the CHANGELOG or README if appropriate --- By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license and I agree to the terms of the [Developer Certificate of Origin (DCO)](https://developercertificate.org/).
