> Key: IGNITE-17149
> URL: https://issues.apache.org/jira/browse/IGNITE-17149
> Project: Ignite
> Issue Type: Task
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko

> *Problem*
> At the moment, the
> *org.apache.ignite.internal.storage.pagememory.configuration.schema.PageMemoryStorageEngineConfigurationSchema*
> contains configuration for in-memory and persistent
> *org.apache.ignite.internal.pagememory.configuration.schema.PageMemoryDataRegionConfigurationSchema*,
> which can be inconvenient for the user for several reasons:
> * *PageMemoryDataRegionConfigurationSchema* contains the configuration for
> in-memory and the persistent case, which can be confusing because it's not
> obvious which properties to set for each;
> * User does not have the ability to set a different size
> *PageMemoryStorageEngineConfigurationSchema#pageSize* for in-memory and the
> persistent case;
> * When creating a table through SQL, it would be more convenient for the
> user to simply specify the engine and use the default region than specify the
> data region, let's look at the examples.
> {code:java}
> CREATE TABLE user (id INT PRIMARY KEY, name VARCHAR(255)) ENGINE pagememory
> dataRegion='in-memory'
> CREATE TABLE user (id INT PRIMARY KEY, name VARCHAR(255)) ENGINE pagememory
> dataRegion='persistnet'{code}
> {code:java}
> CREATE TABLE user (id INT PRIMARY KEY, name VARCHAR(255)) ENGINE
> in-memory-pagememory
> CREATE TABLE user (id INT PRIMARY KEY, name VARCHAR(255)) ENGINE
> persistnet-pagememory
> {code}
> *Implementation proposal*
> Divide by two (in-memory and persistent):
> *
> *org.apache.ignite.internal.pagememory.configuration.schema.PageMemoryDataRegionConfigurationSchema*
> *
> *org.apache.ignite.internal.storage.pagememory.configuration.schema.PageMemoryStorageEngineConfigurationSchema*
> * *org.apache.ignite.internal.storage.pagememory.PageMemoryStorageEngine*
