rules
Key: IGNITE-18211
URL: https://issues.apache.org/jira/browse/IGNITE-18211
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
Need to adjust affinity function to be prepared to upcoming concept of
[Distribution Zones|https://issues.apache.org/jira/browse/IGNITE-17924].
Following changes are required:
* AffinityFunction has to be updated with id (name) of the distribution zone
* (De-)Serialization of the DistributionFunction need to be adjusted as well
* Integration with table
Besides, it looks like the following condition is no more valid, thus should be
removed:
{code:java}
//
org.apache.ignite.internal.sql.engine.trait.TraitUtils#convertDistribution
if (toTrait.function().affinity() && toTrait.getKeys().size() > 1) {
return null;
}
{code}
