Regarding caching during scans there are two types of caches: * caching (bufferring) the records before returning them to the client, enabled via scan.setCaching(numRows) * block cache on a regionserver, enabled via setCacheBlocks(true)
The latter one (block cache) is what you are looking for. Note: setCacheBlocks(true) will not override your columnfamily settings, so do not disable it on that level.
