Amazonka.M2.Types.VsamDetailAttributes

Description

Documentation

data VsamDetailAttributes Source #

The attributes of a VSAM type data set.

See: newVsamDetailAttributes smart constructor.

Constructors

VsamDetailAttributes'

Fields

alternateKeys :: Maybe [AlternateKey]
The alternate key definitions, if any. A legacy dataset might not have any alternate key defined, but if those alternate keys definitions exist, provide them as some applications will make use of them.
cacheAtStartup :: Maybe Bool
If set to True, enforces loading the data set into cache before it’s used by the application.
compressed :: Maybe Bool
Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.
encoding :: Maybe Text
The character set used by the data set. Can be ASCII, EBCDIC, or unknown.
primaryKey :: Maybe PrimaryKey
The primary key of the data set.
recordFormat :: Maybe Text
The record format of the data set.

newVsamDetailAttributes :: VsamDetailAttributes Source #

Create a value of VsamDetailAttributes 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:alternateKeys:VsamDetailAttributes', vsamDetailAttributes_alternateKeys - The alternate key definitions, if any. A legacy dataset might not have any alternate key defined, but if those alternate keys definitions exist, provide them as some applications will make use of them.

$sel:cacheAtStartup:VsamDetailAttributes', vsamDetailAttributes_cacheAtStartup - If set to True, enforces loading the data set into cache before it’s used by the application.

$sel:compressed:VsamDetailAttributes', vsamDetailAttributes_compressed - Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.

$sel:encoding:VsamDetailAttributes', vsamDetailAttributes_encoding - The character set used by the data set. Can be ASCII, EBCDIC, or unknown.

$sel:primaryKey:VsamDetailAttributes', vsamDetailAttributes_primaryKey - The primary key of the data set.

$sel:recordFormat:VsamDetailAttributes', vsamDetailAttributes_recordFormat - The record format of the data set.

vsamDetailAttributes_alternateKeys :: Lens' VsamDetailAttributes (Maybe [AlternateKey]) Source #

If set to True, enforces loading the data set into cache before it’s used by the application.

vsamDetailAttributes_compressed :: Lens' VsamDetailAttributes (Maybe Bool) Source #

Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.

vsamDetailAttributes_encoding :: Lens' VsamDetailAttributes (Maybe Text) Source #

The character set used by the data set. Can be ASCII, EBCDIC, or unknown.

vsamDetailAttributes_primaryKey :: Lens' VsamDetailAttributes (Maybe PrimaryKey) Source #

The primary key of the data set.

vsamDetailAttributes_recordFormat :: Lens' VsamDetailAttributes (Maybe Text) Source #
