Alexander Lapin updated IGNITE-27279:
-------------------------------------
Description:
Currently AI3 uses hard-coded default zone partition count [1]
Instead, partition count should be calculated dynamically, using the formula:
{*}nodes_count * max(cores_count, 8) * scale_coeff{*}, where
* nodes_count is the count of nodes in initial topology
* cores_count is the number of cores per node
* scale_coeff defines cluster upscaling, with default value of (2, 3 or 4 - we
need to run some benchmarks in order to check which is better).
[1]
org.apache.ignite.internal.catalog.commands.CatalogUtils#DEFAULT_PARTITION_COUNT
+ info if the distribution occurred to be inefficient.
