--
-- Returns the current provisioned-capacity quotas for your AWS account in
-- a Region, both for the Region as a whole and for any one DynamoDB table
-- that you create there.
--
-- When you establish an AWS account, the account has initial quotas on the
-- maximum read capacity units and write capacity units that you can
-- provision across all of your DynamoDB tables in a given Region. Also,
-- there are per-table quotas that apply when you create a table there. For
-- more information, see
-- <https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html Service, Account, and Table Quotas>
-- page in the /Amazon DynamoDB Developer Guide/.
--
-- Although you can increase these quotas by filing a case at
-- <https://console.aws.amazon.com/support/home#/ AWS Support Center>,
-- obtaining the increase is not instantaneous. The @DescribeLimits@ action
-- lets you write code to compare the capacity you are currently using to
-- those quotas imposed by your account so that you have enough time to
-- apply for an increase before you hit a quota.
--
-- For example, you could use one of the AWS SDKs to do the following:
--
-- 1.  Call @DescribeLimits@ for a particular Region to obtain your current
--     account quotas on provisioned capacity there.
--
-- 2.  Create a variable to hold the aggregate read capacity units
--     provisioned for all your tables in that Region, and one to hold the
--     aggregate write capacity units. Zero them both.
--
-- 3.  Call @ListTables@ to obtain a list of all your DynamoDB tables.
--
-- 4.  For each table name listed by @ListTables@, do the following:
--
--     -   Call @DescribeTable@ with the table name.
--
--     -   Use the data returned by @DescribeTable@ to add the read
--         capacity units and write capacity units provisioned for the
--         table itself to your variables.
--
--     -   If the table has one or more global secondary indexes (GSIs),
--         loop over these GSIs and add their provisioned capacity values
--         to your variables as well.
--
-- 5.  Report the account quotas for that Region returned by
--     @DescribeLimits@, along with the total current provisioned capacity
--     levels you have calculated.
--
-- This will let you see whether you are getting close to your
-- account-level quotas.
--
-- The per-table quotas apply only when you are creating a new table. They
-- restrict the sum of the provisioned capacity of the new table itself and
-- all its global secondary indexes.
--
-- For existing tables and their GSIs, DynamoDB doesn\'t let you increase
-- provisioned capacity extremely rapidly, but the only quota that applies
-- is that the aggregate provisioned capacity over all your tables and GSIs
-- cannot exceed either of the per-account quotas.
--
-- @DescribeLimits@ should only be called periodically. You can expect
-- throttling errors if you call it more than once in a minute.
--
-- The @DescribeLimits@ Request element has no content.
