> 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||
> |InsertBenchmark.sqlInsert|1|false|1|avgt|20|0.643|± 0.069|ms/op|
> |InsertBenchmark.sqlInsert|1|false|5|avgt|20|0.756|± 0.049|ms/op|
> |InsertBenchmark.sqlInsert|1|false|25|avgt|20|1.114|± 0.093|ms/op|
> |SelectBenchmark.sqlGet|1|false|1|avgt|20|203.432|± 16.617|us/op|
