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) --
