Here are some examples: Here are some examples:
* One region server with the default heap size (1 GB) and the default block cache size will have 253 MB of block cache available. * One region server with the heap size set to 1 GB and the default block cache size will have 253 MB of block cache available.
* 20 region servers with the heap size set to 8 GB and a default block cache size will have 39.6 of block cache. * 20 region servers with the heap size set to 8 GB and a default block cache size will have 39.6 of block cache.
* 100 region servers with the heap size set to 24 GB and a block cache size of 0.5 will have about 1.16 TB of block cache. * 100 region servers with the heap size set to 24 GB and a block cache size of 0.5 will have about 1.16 TB of block cache.
