Subject Re: Which algorithm used in Cube Planner

Hi Kumar,

There are two kinds of algorithms. The cube planner algorithms, greedy & generic (for
large domain), are for cuboid selection. While layered & fast cubing algorithms are for
how to build cuboids.

The idea of fast cubing is to build the whole cuboid lattice in the memory of mappers to speed
up the whole building process.

Subject: Which algorithm used in Cube Planner

Hi,

   Which algorithm used in Cube Planner?

whether  Greedy or Fast Cube or genetic algorithm.

Fast Cube           - In this Algorithm  generate cuboid from Cube
                              http://kylin.apache.org/blog/2015/08/15/fast-cubing/<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fkylin.apache.org%2Fblog%2F2015%2F08%2F15%2Ffast-cubing%2F&data=02%7C01%7Cyangzhong%40ebay.com%7C0d9c85e3da694c320da308d5c20703f4%7C46326bff992841a0baca17c16c94ea99%7C0%7C1%7C636628257739936133&sdata=CkmHJy6AsbXvnmLuB1SCIS2%2FAWOcu8kmcT1D76TDdo4%3D&reserved=0>

Greedy                 -In this Algorithm decided to find cost effective Cuboid.
 Genetic                -In this Algorithm faster than Greedy,but where its used?

Kindly Correct Me what bases  the generate Cube Planner?
