jiazhai opened a new issue #4025: Improve read performance for tiered-storage segment readout URL: https://github.com/apache/pulsar/issues/4025 As discussed in slack channel with @chairmank , Steve suggested that we could do a read-ahead to improve the read performance: ``` I looked at `BlobStoreBackedInputStreamImpl` and `BlobStoreBackedReadHandleImpl` to understand how performance could be improved. I think that reads from blob store would be faster with speculative read-ahead, so that `refillBufferIfNeeded` can swap an already-populated buffer instead of blocking on a call to `blobStore.getBlob`. ```
