/* LY: тест "холмиком":
|
||
* - сначала наполняем таблицу циклическими CRUD-манипуляциями,
|
||
* которые в каждом цикле делают несколько операций, включая удаление,
|
||
* но в результате добавляют записи.
|
||
* - затем очищаем таблицу также CRUD-манипуляциями, но уже с другой
|
||
* пропорцией удалений.
|
||
*
|
||
* При этом очень многое зависит от порядка перебора ключей:
|
||
* - (псевдо)случайное распределение требуется лишь для полноты картины,
|
||
* но в целом не покрывает важных кейсов.
|
||
* - кроме (псевдо)случайного перебора требуется последовательное
|
||
* итерирование ключей интервалами различной ширины, с тем чтобы
|
||
* проверить различные варианты как разделения, так и слияния страниц
|
||
* внутри движка.
|
||
* - при не-уникальных ключах (MDBX_DUPSORT с подвариантами), для каждого
|
||
* повтора внутри движка формируется вложенное btree-дерево,
|
||
* соответственно требуется соблюдение аналогичных принципов
|
||
* итерирования для значений.
