@JvmName(name = "lmqfbuamuhecyrbk")
suspend fun key(value: String)

Parameters

value

The key of the dataset contents object in an S3 bucket. Each object has a key that is a unique identifier. Each object has exactly one key. You can create a unique key with the following options:

  • Use !{iotanalytics:scheduleTime} to insert the time of a scheduled SQL query run.

  • Use !{iotanalytics:versionId} to insert a unique hash that identifies a dataset content.

  • Use !{iotanalytics:creationTime} to insert the creation time of a dataset content. The following example creates a unique key for a CSV file: dataset/mydataset/!{iotanalytics:scheduleTime}/!{iotanalytics:versionId}.csv

If you don't use !{iotanalytics:versionId} to specify the key, you might get duplicate keys. For example, you might have two dataset contents with the same scheduleTime but different versionId s. This means that one dataset content overwrites the other.
