### <a name="on-demand"></a> On-Demand Dynamo Capacity
|
||||
|
||||
[Amazon DynamoDB On-Demand](https://aws.amazon.com/blogs/aws/amazon-dynamodb-on-demand-no-capacity-planning-and-pay-per-request-pricing/)
|
||||
removes the need to pre-allocate I/O capacity for S3Guard tables.
|
||||
Instead the caller is _only_ charged per I/O Operation.
|
||||
|
||||
* There are no SLA capacity guarantees. This is generally not an issue
|
||||
for S3Guard applications.
|
||||
* There's no explicit limit on I/O capacity, so operations which make
|
||||
heavy use of S3Guard tables (for example: SQL query planning) do not
|
||||
get throttled.
|
||||
* There's no way put a limit on the I/O; you may unintentionally run up
|
||||
large bills through sustained heavy load.
|
||||
* The `s3guard set-capacity` command fails: it does not make sense any more.
|
||||
|
||||
When idle, S3Guard tables are only billed for the data stored, not for
|
||||
any unused capacity. For this reason, there is no benefit from sharing
|
||||
a single S3Guard table across multiple buckets.
|
||||
|
||||
*Enabling DynamoDB On-Demand for a S3Guard table*
|
||||
|
||||
You cannot currently enable DynamoDB on-demand from the `s3guard` command
|
||||
when creating or updating a bucket.
|
||||
|
||||
Instead it must be done through the AWS console or [the CLI](https://docs.aws.amazon.com/cli/latest/reference/dynamodb/update-table.html).
|
||||
From the Web console or the command line, switch the billing to pay-per-request.
|
||||
|
||||
Once enabled, the read and write capacities of the table listed in the
|
||||
`hadoop s3guard bucket-info` command become "0", and the "billing-mode"
|
||||
attribute changes to "per-request":

### <a name="autoscaling"></a> Autoscaling S3Guard tables.
|
||||
|
||||
[DynamoDB Auto Scaling](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.html)
|
||||
can automatically increase and decrease the allocated capacity.
|
||||
This is good for keeping capacity high when needed, but avoiding large
|
||||
bills when it is not.
|
||||
|
||||
Before DynamoDB On-Demand was introduced, autoscaling was the sole form
|
||||
of dynamic scaling.
|
||||
|
||||
Experiments with S3Guard and DynamoDB Auto Scaling have shown that any Auto Scaling
|
||||
operation will only take place after callers have been throttled for a period of
|
||||
time. The clients will still need to be configured to retry when overloaded
|
||||
until any extra capacity is allocated. Furthermore, as this retrying will
|
||||
block the threads from performing other operations -including more IO, the
|
||||
block the threads from performing other operations -including more I/O, the
|
||||
the autoscale may not scale fast enough.
|
||||
|
||||
We recommend experimenting with this, based on usage information collected
|
||||
from previous days, and and choosing a combination of
|
||||
retry counts and an interval which allow for the clients to cope with
|
||||
some throttling, but not to time out other applications.
|
||||
This is why the DynamoDB On-Demand appears to be a better option for
|
||||
workloads with Hadoop, Spark, Hive and other applications.

||||
If autoscaling is to be used, we recommend experimenting with the option,

based on usage information collected from previous days, and choosing a

combination of retry counts and an interval which allow for the clients to cope with
