Request Syntax

response = client.describe_cache_engine_versions(
    Engine='string',
    EngineVersion='string',
    CacheParameterGroupFamily='string',
    MaxRecords=123,
    Marker='string',
    DefaultOnly=True|False
)

Parameters:

• Engine (string) – The cache engine to return. Valid values: memcached | redis

• EngineVersion (string) –

  The cache engine version to return.

  Example: 1.4.14

• CacheParameterGroupFamily (string) –

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

  Valid values are: memcached1.4 | memcached1.5 | memcached1.6 | redis2.6 | redis2.8 | redis3.2 | redis4.0 | redis5.0 | redis6.x | redis6.2 | redis7

  Constraints:

  • Must be 1 to 255 alphanumeric characters

  • First character must be a letter

  • Cannot end with a hyphen or contain two consecutive hyphens

• MaxRecords (integer) –

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

  Default: 100

  Constraints: minimum 20; maximum 100.

• Marker (string) – An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

• DefaultOnly (boolean) – If true, specifies that only the default version of the specified engine or engine and major version combination is to be returned.

Return type:

dict
