# DynamoDB Kinesis Streaming Destination Precision Compatibility Test
|
|
#
|
|
# EnableKinesisStreamingDestination ignored ApproximateCreationDateTimePrecision, and
|
|
# DescribeKinesisStreamingDestination always reported MILLISECOND. The provider marks
|
|
# approximate_creation_date_time_precision as ForceNew, so a MICROSECOND destination read back
|
|
# as MILLISECOND and was destroyed and recreated on every apply. Enabling the destination also
|
|
# switched on DynamoDB Streams for the table, so aws_dynamodb_table planned to turn it back off
|
|
# on every run. This verifies the precision reads back as written, a second plan is clean for
|
|
# both resources, and changing the precision replaces the destination once.
