    <p>I am processing a large set of files as follows: I first download all of them to an EC2 instance and then I run a script that sequentially processes each file and indexes it into a DynamoDDB table (each item in the table corresponds to a single line in a file). Then I download the next batch of files etc.</p> <p>Right now I adjust provisioned throughput via AWS GUI console and it ends up being the same during both the download phase and the indexing phase. Clearly, this is suboptimal since while downloading I do not talk to the database at all so my required write throughput during this phase is essentially 0.</p> <p>So what I want to do is programmatically adjust provisioned throughput way up when I start indexing and then way down when I stop indexing and start downloading.</p> <p>Are there any limits on how much I can increase write t/p in a single request? For instance, can I change it from 5 to 120? If not, how do i calculate the number of requests and the time required to adjust t/p from value X to value Y (where X &lt;&lt; Y)? Do I have to do similar calculation for decreasing t/p?</p> <p>I am using Python boto.</p> <p>Thanks </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
