<p>A filter that specifies one or more DB engine versions to describe.</p> <p>Supported filters:</p> <ul> <li> <p> <code>db-parameter-group-family</code> - Accepts parameter groups family names.

<p>The maximum number of records to include in the response. If more than the <code>MaxRecords</code> value is available, a pagination token called a marker is included in the response so you can retrieve the remaining results.</p> <p>Default: 100</p> <p>Constraints: Minimum 20, maximum 100.</p>

An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by <code>MaxRecords</code>.

A value that indicates whether only the default version of the specified engine or engine and major version combination is returned.

<p>A value that indicates whether to list the supported character sets for each engine version.</p> <p>If this parameter is enabled and the requested engine supports the <code>CharacterSetName</code> parameter for <code>CreateDBInstance</code>, the response includes a list of supported character sets for each engine version.</p> <p>For RDS Custom, the default is not to list supported character sets.

<p>A value that indicates whether to list the supported time zones for each engine version.</p> <p>If this parameter is enabled and the requested engine supports the <code>TimeZone</code> parameter for <code>CreateDBInstance</code>, the response includes a list of supported time zones for each engine version.</p> <p>For RDS Custom, the default is not to list supported time zones.
