update_table#

TimestreamWrite.Client.update_table(**kwargs)#

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.

See code sample for details.

Parameters:

DatabaseName (string) –
[REQUIRED]

The name of the Timestream database.
TableName (string) –
[REQUIRED]

The name of the Timestream table.
RetentionProperties (dict) –
The retention duration of the memory store and the magnetic store.
- MemoryStoreRetentionPeriodInHours (integer) – [REQUIRED]
  
  The duration for which data must be stored in the memory store.
- MagneticStoreRetentionPeriodInDays (integer) – [REQUIRED]
  
  The duration for which data must be stored in the magnetic store.
MagneticStoreWriteProperties (dict) –
Contains properties to set on the table when enabling magnetic store writes.
- EnableMagneticStoreWrites (boolean) – [REQUIRED]
  
  A flag to enable magnetic store writes.
- MagneticStoreRejectedDataLocation (dict) –
  
  The location to write error reports for records rejected asynchronously during magnetic store writes.
  - S3Configuration (dict) –
    
    Configuration of an S3 location to write error reports for records rejected, asynchronously, during magnetic store writes.
    - BucketName (string) –
      
      The bucket name of the customer S3 bucket.
    - ObjectKeyPrefix (string) –
      
      The object key preview for the customer S3 location.
    - EncryptionOption (string) –
      
      The encryption option for the customer S3 location. Options are S3 server-side encryption with an S3 managed key or Amazon Web Services managed key.
    - KmsKeyId (string) –
      
      The KMS key ID for the customer S3 location when encrypting with an Amazon Web Services managed key.
Schema (dict) –
The schema of the table.
- CompositePartitionKey (list) –
  
  A non-empty list of partition keys defining the attributes used to partition the table data. The order of the list determines the partition hierarchy. The name and type of each partition key as well as the partition key order cannot be changed after the table is created. However, the enforcement level of each partition key can be changed.
  - (dict) –
    
    An attribute used in partitioning data in a table. A dimension key partitions data using the values of the dimension specified by the dimension-name as partition key, while a measure key partitions data using measure names (values of the ‘measure_name’ column).
    - Type (string) – [REQUIRED]
      
      The type of the partition key. Options are DIMENSION (dimension key) and MEASURE (measure key).
    - Name (string) –
      
      The name of the attribute used for a dimension key.
    - EnforcementInRecord (string) –
      
      The level of enforcement for the specification of a dimension key in ingested records. Options are REQUIRED (dimension key must be specified) and OPTIONAL (dimension key does not have to be specified).

Return type:
