             Summary: Benchmark sorted index scan vs table's partitions scan
                 Key: IGNITE-14936
                 URL: https://issues.apache.org/jira/browse/IGNITE-14936
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Taras Ledkov
             Fix For: 3.0.0-alpha3


We have to decide what are data structures is used for PK and table scan.
Possible cases:
- table partitions sorted by plain bytes/hash (in fact: unsorted);
- table partitions sorted by PK columns;
- PK sorted index (one store for all partitions on the node).

All cases have pros and cons. The choice should be based on benchmarks.
