extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<PerformanceInsightsMetricDimensionGroup.Builder,PerformanceInsightsMetricDimensionGroup>
```
A logical grouping of Performance Insights metrics for a related subject area. For example, the db.sql dimension group consists of the following dimensions: db.sql.id, db.sql.db_id, db.sql.statement, and db.sql.tokenized_id.

Each response element returns a maximum of 500 bytes. For larger elements, such as SQL statements, only the first 500 bytes are returned.

Amazon RDS Performance Insights enables you to monitor and explore different dimensions of database load based on data captured from a running DB instance. DB load is measured as average active sessions. Performance Insights provides the data to API consumers as a two-dimensional time-series dataset. The time dimension provides DB load data for each time point in the queried time range. Each time point decomposes overall load in relation to the requested dimensions, measured at that time point. Examples include SQL, Wait event, User, and Host.

- Method Detail
  - group
```
public final String group()
```
    The name of the dimension group. Its valid values are:
    
    db - The name of the database to which the client is connected (only Aurora PostgreSQL, Amazon RDS PostgreSQL, Aurora MySQL, Amazon RDS MySQL, and MariaDB)
    
    db.application - The name of the application that is connected to the database (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.host - The host name of the connected client (all engines)
    
    db.session_type - The type of the current session (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.sql - The SQL that is currently executing (all engines)
    
    db.sql_tokenized - The SQL digest (all engines)
    
    db.wait_event - The event for which the database backend is waiting (all engines)
    
    db.wait_event_type - The type of event for which the database backend is waiting (all engines)
    
    db.user - The user logged in to the database (all engines)
    Returns:
    
    The name of the dimension group. Its valid values are:
    
    db - The name of the database to which the client is connected (only Aurora PostgreSQL, Amazon RDS PostgreSQL, Aurora MySQL, Amazon RDS MySQL, and MariaDB)
    
    db.application - The name of the application that is connected to the database (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.host - The host name of the connected client (all engines)
    
    db.session_type - The type of the current session (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.sql - The SQL that is currently executing (all engines)
    
    db.sql_tokenized - The SQL digest (all engines)
    
    db.wait_event - The event for which the database backend is waiting (all engines)
    
    db.wait_event_type - The type of event for which the database backend is waiting (all engines)
    
    db.user - The user logged in to the database (all engines)
  - hasDimensions
```
public final boolean hasDimensions()
```
    For responses, this returns true if the service returned a value for the Dimensions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - dimensions
```
public final List<String> dimensions()
```
    A list of specific dimensions from a dimension group. If this parameter is not present, then it signifies that all of the dimensions in the group were requested or are present in the response.
    
    Valid values for elements in the Dimensions array are:
    
    db.application.name - The name of the application that is connected to the database (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.host.id - The host ID of the connected client (all engines)
    
    db.host.name - The host name of the connected client (all engines)
    
    db.name - The name of the database to which the client is connected (only Aurora PostgreSQL, Amazon RDS PostgreSQL, Aurora MySQL, Amazon RDS MySQL, and MariaDB)
    
    db.session_type.name - The type of the current session (only Aurora PostgreSQL and RDS PostgreSQL)
    
    db.sql.id - The SQL ID generated by Performance Insights (all engines)
    
    db.sql.db_id - The SQL ID generated by the database (all engines)
    
    db.sql.statement - The SQL text that is being executed (all engines)
    
    db.sql.tokenized_id
    
    db.sql_tokenized.id - The SQL digest ID generated by Performance Insights (all engines)
    
    db.sql_tokenized.db_id - SQL digest ID generated by the database (all engines)
    
    db.sql_tokenized.statement - The SQL digest text (all engines)
    
    db.user.id - The ID of the user logged in to the database (all engines)
    
    db.user.name - The name of the user logged in to the database (all engines)
    
    db.wait_event.name - The event for which the backend is waiting (all engines)
    
    db.wait_event.type - The type of event for which the backend is waiting (all engines)
    
    db.wait_event_type.name - The name of the event type for which the backend is waiting (all engines)
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasDimensions() method.
    Returns:
    
    A list of specific dimensions from a dimension group. If this parameter is not present, then it signifies that all of the dimensions in the group were requested or are present in the response.

    db.host.name - The host name of the connected client (all engines)
    
    db.name - The name of the database to which the client is connected (only Aurora PostgreSQL, Amazon RDS PostgreSQL, Aurora MySQL, Amazon RDS MySQL, and MariaDB)
