Interface ByteBufferPoolProvider

All Known Implementing Classes:
SnapshotBufferManager
public interface ByteBufferPoolProvider
Provides specialized byte buffer pools optimized for different I/O operations. This interface serves as a factory for obtaining buffer pools configured for:
  • Encryption operations (with algorithm-specific sizing)
  • High-performance disk writes (when NodeSnapshotConfiguration.snapshotDiskBufferSizeBytes() coincides with OS page size)

All returned buffer pools are configured according to NodeSnapshotConfiguration.

  • Method Details

    • encryptionPool

      EncryptionByteBufferPool encryptionPool(Cipher cipher)
      Provides a buffer pool configured for cryptographic operations using the specified cipher. The returned pool manages buffers that comply with:
      • Algorithm-specific block size requirements
      • Input/output size constraints for the cipher
      • Padding requirements for complete blocks
      Parameters:
      cipher - the cryptographic cipher that determines buffer sizing requirements.
      Returns:
      configured buffer pool for encryption/decryption operations.

    • flushToDiskPool

      ByteBufferPool flushToDiskPool()
      Provides a buffer pool optimized for disk write operations. The pool features:
      • Configurable pool size and buffers based on NodeSnapshotConfiguration
      • Buffers sized to minimize write amplification
      Returns:
      buffer pool optimized for disk I/O operations
