StreamRecord'

Fields

sizeBytes :: Maybe Natural
The size of the stream record, in bytes.
sequenceNumber :: Maybe Text
The sequence number of the stream record.
approximateCreationDateTime :: Maybe POSIX
The approximate date and time when the stream record was created, in UNIX epoch time format.
streamViewType :: Maybe StreamViewType
The type of data from the modified DynamoDB item that was captured in this stream record:
- KEYS_ONLY - only the key attributes of the modified item.
- NEW_IMAGE - the entire item, as it appeared after it was modified.
- OLD_IMAGE - the entire item, as it appeared before it was modified.
- NEW_AND_OLD_IMAGES - both the new and the old item images of the item.
keys :: Maybe (HashMap Text AttributeValue)
The primary key attribute(s) for the DynamoDB item that was modified.
oldImage :: Maybe (HashMap Text AttributeValue)
The item in the DynamoDB table as it appeared before it was modified.
newImage' :: Maybe (HashMap Text AttributeValue)
The item in the DynamoDB table as it appeared after it was modified.

newStreamRecord :: StreamRecord Source #

Create a value of StreamRecord 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:sizeBytes:StreamRecord', streamRecord_sizeBytes - The size of the stream record, in bytes.

$sel:sequenceNumber:StreamRecord', streamRecord_sequenceNumber - The sequence number of the stream record.

$sel:approximateCreationDateTime:StreamRecord', streamRecord_approximateCreationDateTime - The approximate date and time when the stream record was created, in UNIX epoch time format.

$sel:streamViewType:StreamRecord', streamRecord_streamViewType - The type of data from the modified DynamoDB item that was captured in this stream record:

KEYS_ONLY - only the key attributes of the modified item.
NEW_IMAGE - the entire item, as it appeared after it was modified.
OLD_IMAGE - the entire item, as it appeared before it was modified.
NEW_AND_OLD_IMAGES - both the new and the old item images of the item.

$sel:keys:StreamRecord', streamRecord_keys - The primary key attribute(s) for the DynamoDB item that was modified.

$sel:oldImage:StreamRecord', streamRecord_oldImage - The item in the DynamoDB table as it appeared before it was modified.

$sel:newImage':StreamRecord', streamRecord_newImage - The item in the DynamoDB table as it appeared after it was modified.
