Modifier and Type	Method and Description
void	CombinedBlockCache.cacheBlock(BlockCacheKey cacheKey, Cacheable buf)
void	LruBlockCache.cacheBlock(BlockCacheKey cacheKey, Cacheable buf) Cache the block with the specified name and buffer.

void	CombinedBlockCache.returnBlock(BlockCacheKey cacheKey, Cacheable block)
default void	BlockCache.returnBlock(BlockCacheKey cacheKey, Cacheable block) Called when the scanner using the block decides to return the block once its usage is over.
static boolean	BlockCacheUtil.shouldReplaceExistingCacheBlock(BlockCache blockCache, BlockCacheKey cacheKey, Cacheable newBlock) Because of the region splitting, it's possible that the split key locate in the middle of a block.
static int	BlockCacheUtil.validateBlockAddition(Cacheable existing, Cacheable newBlock, BlockCacheKey cacheKey) Validate that the existing and newBlock are the same without including the nextBlockMetadata, if not, throw an exception.
