Vladislav Pyatkov updated IGNITE-22128:
---------------------------------------
Description:
h3. Motivation
Right now, we use a hash to balance partitions.
{code:java}
public int getStripe(NodeId nodeId) {
return Math.abs(nodeId.hashCode() % stripes);
}
{code}
This approach might lead to a skew.
h3. Definition of done
Partition is distributed statically by the honest round-robin algorithm.
