| * MSLAB - Okay to leave it turned ON 0.92.2 onwards since we have lots of memory and number of regions per region server is not too crazy high (200 regions/per RS) | |
| * Distributed splitting - Want it! | |
| * Memory accounting is different now - Okay to leave block cache's value same as it was in 0.90.0 since its already set to a liberal value (0.45) | |
| * Experimental off-heap cache - Leave it turned off. | |
| * Region max file size - Currently set to 2GB, we should go up. 4GB will cut our regions / per region server to under 100. |
