The implementation reduces the complexity in DataBlockManager and makes the optimization logic more testable. Changes are: - Adds readAheadBytes logic - Adds sequential prefetching logic - Groups sequential block indexes together - Splits large sequential groups into smaller chunks based on configuration parameters - Refactored DataBlockManager to use the new method instead of implementing the logic itself - Added comprehensive unit tests for the new method Out of Scope - Range coalescing will be implemented in a separate PR #### Relevant issues PR History: https://github.com/awslabs/analytics-accelerator-s3/pull/286 https://github.com/awslabs/analytics-accelerator-s3/pull/287 https://github.com/awslabs/analytics-accelerator-s3/pull/288 #### Does this contribution introduce any breaking changes to the existing APIs or behaviors?

S3A currently has this customer key as Optional String https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/auth/delegation/EncryptionSecretOperations.java#L41 while Iceberg has this key as a String https://github.com/apache/iceberg/blob/f9cc62eb0d98e360b452a3ab8fdc6efdc4969f6e/aws/src/main/java/org/apache/iceberg/aws/s3/S3FileIOProperties.java#L499.

[RangeReadable in Iceberg](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/io/RangeReadable.java#L47) **Note:** Here's the comparison with existing read method: | Aspect | `read(byte[] buffer, int offset, int length)` | `readFully(long position, byte[] buffer, int offset, int length)` | |--------|----------------------------------------------|-------------------------------------------------------------------| | Method Signature | Reads from current stream position | Reads from specified position | | Position Behavior | Advances the stream position by the number of bytes actually read | Does not modify the stream position (position-independent read) | | Return & Error Handling | Returns `int` indicating bytes read; returns -1 at end of stream; may return fewer bytes than requested | Returns `void`; throws `IOException` if unable to read exact number of requested bytes | #### Relevant issues Once this feature is released as `1.2.0`, we will update this [Iceberg PR](https://github.com/apache/iceberg/pull/13361) #### Does this contribution introduce any breaking changes to the existing APIs or behaviors? No #### Does this contribution introduce any new public APIs or behaviors? Yes #### How was the contribution tested?
