Record represents a time series data point being written into Timestream. Each record contains an array of dimensions. Dimensions represent the meta data 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. A record also contains the measure value and the value type which is the data type of the measure value. In addition, the record contains the timestamp when the measure was collected that 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
1 for records without the
Contains the list of dimensions for time series data points.
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.
Contains the measure value for the time series data point.
Contains the data type of the measure value for the time series data point. Default type is
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.
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
12345 ms have elapsed since the epoch.
The granularity of the timestamp unit. It indicates if the time value is in seconds, milliseconds, nanoseconds or other supported values.
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
Version must be
1 or greater, or you will receive a
