### Before Creating the Enhancement Request - [x] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary Currently, `IndexStoreFile` always uses `ByteBuffer` (MappedByteBuffer) for writing operations, even when `writeWithoutMmap` is enabled in the store configuration. This prevents users from using FileChannel-based writing in IndexStoreFile, which can be beneficial in certain scenarios where mmap is not desired. ### Motivation Currently, `IndexStoreFile` always uses `ByteBuffer` (MappedByteBuffer) for writing operations, even when `writeWithoutMmap` is enabled in the store configuration. This prevents users from using FileChannel-based writing in IndexStoreFile, which can be beneficial in certain scenarios where mmap is not desired. ### Describe the Solution You'd Like When `writeWithoutMmap` is enabled in `MessageStoreConfig`, `IndexStoreFile` should use `FileChannel` for all write operations instead of `ByteBuffer`. ### Describe Alternatives You've Considered No ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
