Record

Represents a time-series data point being written into Timestream. Each record contains an array of dimensions. Dimensions represent the metadata attributes of a time-series data point, such as the instance name or Availability Zone of an EC2 instance. A record also contains the measure name, which is the name of the measure being collected (for example, the CPU utilization of an EC2 instance). Additionally, a record contains the measure value and the value type, which is the data type of the measure value. Also, the record contains the timestamp of when the measure was collected and the timestamp unit, which represents the granularity of the timestamp.

Records have a Version field, which is a 64-bit long that you can use for updating data points. Writes of a duplicate record with the same dimension, timestamp, and measure name but different measure value will only succeed if the Version attribute of the record in the write request is higher than that of the existing record. Timestream defaults to a Version of 1 for records without the Version field.

Dimensions

Contains the list of dimensions for time-series data points.

Type: Array of Dimension objects

Array Members: Maximum number of 128 items.

Required: No

MeasureName

Measure represents the data attribute of the time series. For example, the CPU utilization of an EC2 instance or the RPM of a wind turbine are measures.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

MeasureValue

Contains the measure value for the time-series data point.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: No

MeasureValues

Contains the list of MeasureValue for time-series data points.

This is only allowed for type MULTI. For scalar values, use MeasureValue attribute of the record directly.

Type: Array of MeasureValue objects

Required: No

MeasureValueType

Contains the data type of the measure value for the time-series data point. Default type is DOUBLE. For more information, see Data types.

Type: String

Required: No

Time

Contains the time at which the measure value for the data point was collected. The time value plus the unit provides the time elapsed since the epoch. For example, if the time value is 12345 and the unit is ms, then 12345 ms have elapsed since the epoch.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

TimeUnit

The granularity of the timestamp unit. It indicates if the time value is in seconds, milliseconds, nanoseconds, or other supported values. Default is MILLISECONDS.

Type: String

Valid Values: MILLISECONDS | SECONDS | MICROSECONDS | NANOSECONDS

Required: No

Version

64-bit attribute used for record updates. Write requests for duplicate data with a higher version number will update the existing measure value and version. In cases where the measure value is the same, Version will still be updated. Default value is 1.

Note

Version must be 1 or greater, or you will receive a ValidationException error.

Type: Long

Required: No
