2021/11/24 - Amazon Timestream Write - 5 updated api methods
Changes This release adds support for multi-measure records and magnetic store writes. Multi-measure records allow customers to store multiple measures in a single table row. Magnetic store writes enable customers to write late arrival data (data with timestamp in the past) directly into the magnetic store.

The CreateTable operation adds a new table to an existing database in your account. In an Amazon Web Services account, table names must be at least unique within each Region if they are in the same database. You may have identical table names in the same Region if the tables are in separate databases. While creating the table, you must specify the table name, database name, and the retention properties. Service quotas apply. See code sample for details.

Modifies the retention duration of the memory store and magnetic store for your Timestream table. Note that the change in retention duration takes effect immediately. For example, if the retention period of the memory store was initially set to 2 hours and then changed to 24 hours, the memory store will be capable of holding 24 hours of data, but will be populated with 24 hours of data 22 hours after this change was made. Timestream does not retrieve data from the magnetic store to populate the memory store.

The WriteRecords operation enables you to write your time series data into Timestream. You can specify a single data point or a batch of data points to be inserted into the system. Timestream offers you with a flexible schema that auto detects the column names and data types for your Timestream tables based on the dimension names and data types of the data points you specify when invoking writes into the database. Timestream support eventual consistency read semantics. This means that when you query data immediately after writing a batch of data into Timestream, the query results might not reflect the results of a recently completed write operation. The results may also include some stale data. If you repeat the query request after a short time, the results should return the latest data. Service quotas apply.
See code sample for details.
Upserts
You can use the Version parameter in a WriteRecords request to update data points. Timestream tracks a version number with each record. Version defaults to 1 when not specified for the record in the request. Timestream will update an existing record’s measure value along with its Version upon receiving a write request with a higher Version number for that record. Upon receiving an update request where the measure value is the same as that of the existing record, Timestream still updates Version, if it is greater than the existing value of Version. You can update a data point as many times as desired, as long as the value of Version continuously increases.
For example, suppose you write a new record without indicating Version in the request. Timestream will store this record, and set Version to 1. Now, suppose you try to update this record with a WriteRecords request of the same record with a different measure value but, like before, do not provide Version. In this case, Timestream will reject this update with a RejectedRecordsException since the updated record’s version is not greater than the existing value of Version. However, if you were to resend the update request with Version set to 2, Timestream would then succeed in updating the record’s value, and the Version would be set to 2. Next, suppose you sent a WriteRecords request with this same record and an identical measure value, but with Version set to 3. In this case, Timestream would only update Version to 3. Any further updates would need to send a version number greater than 3, or the update requests would receive a RejectedRecordsException.

A record containing the common measure, dimension, time, and version attributes shared across all the records in the request. The measure and dimension attributes specified will be merged with the measure and dimension attributes in the records object when the data is written into Timestream. Dimensions may not overlap, or a ValidationException will be thrown. In other words, a record must contain dimensions with unique names.
Dimensions (list) --
Contains the list of dimensions for time series data points.
(dict) --
Dimension represents the meta data attributes of the time series. For example, the name and availability zone of an EC2 instance or the name of the manufacturer of a wind turbine are dimensions.
Name (string) -- [REQUIRED]
Dimension represents the meta data attributes of the time series. For example, the name and availability zone of an EC2 instance or the name of the manufacturer of a wind turbine are dimensions.
For constraints on Dimension names, see Naming Constraints.
Value (string) -- [REQUIRED]
The value of the dimension.
DimensionValueType (string) --
The data type of the dimension for the time series data point.
MeasureName (string) --
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.
MeasureValue (string) --
Contains the measure value for the time series data point.
MeasureValueType (string) --
Contains the data type of the measure value for the time series data point. Default type is DOUBLE.
Time (string) --
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.
TimeUnit (string) --
The granularity of the timestamp unit. It indicates if the time value is in seconds, milliseconds, nanoseconds or other supported values. Default is MILLISECONDS.
Version (integer) --
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.
MeasureValues (list) --
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.
(dict) --
MeasureValue 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. MeasureValue has both name and value.
MeasureValue is only allowed for type MULTI. Using MULTI type, you can pass multiple data attributes associated with the same time series in a single record
Name (string) -- [REQUIRED]
Name of the MeasureValue.
For constraints on MeasureValue names, refer to Naming Constraints in the Timestream developer guide.
Value (string) -- [REQUIRED]
Value for the MeasureValue.

list
[REQUIRED]
An array of records containing the unique measure, dimension, time, and version attributes for each time series data point.
(dict) --
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 Version of 1 for records without the Version field.
