> Key: IGNITE-20812
> URL: https://issues.apache.org/jira/browse/IGNITE-20812
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Konstantin Orlov
> Priority: Major
> Labels: ignite-3
>
> Performance of INSERT and SELECT by primary key queries is affected by number
> of partitions in the table. Most probably, the reason is a lack of partition
> pruning in sql engine.
> Let's investigate and fix the problem.
> Here is a result of local (on my laptop; 2,6 GHz 6-Core Intel Core i7 32GB
> RAM) benchmark:
> ||Benchmark||(clusterSize)||(fsync)||(partitionCount)||Mode||Cnt||Score||Error||Units||
