-------------------
|
||
|
||
Содержит информацию о внешних словарях.
|
||
|
||
Столбцы:
|
||
|
||
.. code-block:: text
|
||
|
||
name String - имя словаря
|
||
type String - тип словаря: Flat, Hashed, Cache
|
||
origin String - путь к конфигурационному файлу, в котором описан словарь
|
||
attribute.names Array(String) - массив имён атрибутов, предоставляемых словарём
|
||
attribute.types Array(String) - соответствующий массив типов атрибутов, предоставляемых словарём
|
||
has_hierarchy UInt8 - является ли словарь иерархическим
|
||
bytes_allocated UInt64 - количество оперативной памяти, которое использует словарь
|
||
hit_rate Float64 - для cache-словарей - доля использований, для которых значение было в кэше
|
||
element_count UInt64 - количество хранящихся в словаре элементов
|
||
load_factor Float64 - доля заполненности словаря (для hashed словаря - доля заполнения хэш-таблицы)
|
||
creation_time DateTime - время создания или последней успешной перезагрузки словаря
|
||
last_exception String - текст ошибки, возникшей при создании или перезагрузке словаря, если словарь не удалось создать
|
||
source String - текст, описывающий источник данных для словаря
|
||
|
||
Заметим, что количество оперативной памяти, которое использует словарь, не является пропорциональным количеству элементов, хранящихся в словаре. Так, для flat и cached словарей, все ячейки памяти выделяются заранее, независимо от реальной заполненности словаря.
