table's partitions scan
Taras Ledkov created IGNITE-14936:
-------------------------------------
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.
