List of cacheBlock() Examples

Examples of cacheBlock()

org.apache.accumulo.core.file.blockfile.cache.LruBlockCache.cacheBlock()
Cache the block with the specified name and buffer.
It is assumed this will NEVER be called on an already cached block. If that is done, it is assumed that you are reinserting the same exact block due to a race condition and will update the buffer but not modify the size of the cache. @param blockName block name @param buf block buffer @param inMemory if block is in-memory

    Block[] blocks = generateFixedBlocks(10, blockSize, "block");
