/*
|
|
* Choosing a Primary Key that Differs from the Sorting Key
|
|
* It is possible to specify a primary key (an expression with values that are written in the index file for each mark)
|
|
* that is different from the sorting key (an expression for sorting the rows in data parts).
|
|
* In this case the primary key expression tuple must be a prefix of the sorting key expression tuple.
|
|
* This feature is helpful when using the SummingMergeTree and AggregatingMergeTree table engines.
|
|
* In a common case when using these engines, the table has two types of columns: dimensions and measures.
|
|
* Typical queries aggregate values of measure columns with arbitrary GROUP BY and filtering by dimensions.
|
|
* Because SummingMergeTree and AggregatingMergeTree aggregate rows with the same value of the sorting key,
|
|
* it is natural to add all dimensions to it. As a result, the key expression consists of a long list of columns
|
|
* and this list must be frequently updated with newly added dimensions.
|
|
* In this case it makes sense to leave only a few columns in the primary key that will provide efficient
|
|
* range scans and add the remaining dimension columns to the sorting key tuple.
|
|
* ALTER of the sorting key is a lightweight operation because when a new column is simultaneously added t
|
|
* o the table and to the sorting key, existing data parts don't need to be changed.
|
|
* Since the old sorting key is a prefix of the new sorting key and there is no data in the newly added column,
|
|
* the data is sorted by both the old and new sorting keys at the moment of table modification.
|
|
