Amazonka.MemoryDb.DescribeEngineVersions

Returns a list of the available Redis engine versions.

This operation returns paginated results.

Creating a Request

data DescribeEngineVersions

See: newDescribeEngineVersions smart constructor.

DescribeEngineVersions'

Fields

• defaultOnly :: Maybe Bool

  If true, specifies that only the default version of the specified engine or engine and major version combination is to be returned.

• engineVersion :: Maybe Text

  The Redis engine version

• maxResults :: Maybe Int

  The maximum number of records to include in the response. If more records exist than the specified MaxResults value, a token is included in the response so that the remaining results can be retrieved.

• nextToken :: Maybe Text

  An optional argument to pass in case the total number of records exceeds the value of MaxResults. If nextToken is returned, there are more results available. The value of nextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged.

• parameterGroupFamily :: Maybe Text

  The name of a specific parameter group family to return details for.

newDescribeEngineVersions :: DescribeEngineVersions

Create a value of DescribeEngineVersions with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:defaultOnly:DescribeEngineVersions', describeEngineVersions_defaultOnly - If true, specifies that only the default version of the specified engine or engine and major version combination is to be returned.

DescribeEngineVersions, describeEngineVersions_engineVersion - The Redis engine version

$sel:maxResults:DescribeEngineVersions', describeEngineVersions_maxResults - The maximum number of records to include in the response. If more records exist than the specified MaxResults value, a token is included in the response so that the remaining results can be retrieved.

DescribeEngineVersions, describeEngineVersions_nextToken - An optional argument to pass in case the total number of records exceeds the value of MaxResults. If nextToken is returned, there are more results available. The value of nextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged.

DescribeEngineVersions, describeEngineVersions_parameterGroupFamily - The name of a specific parameter group family to return details for.
