# [DRILL-8342](https://issues.apache.org/jira/browse/DRILL-8342): Add
Automatic Retry for Rate Limited APIs
## Description
Many APIs have a burst limit for number of requests. This PR adds a retry
capability to the HTTP Storage Plugin, whereby if a 429 response code is
received, Drill will wait a configurable amount of time, and retry the request
once.
To prevent runaway pagination, this retry will only happen once per request.
This PR adds a new configuration option called retryDelay which is the
number of milliseconds that Drill should wait between retrys.
## Documentation
When using automatic pagination, you may encounter APIs that have burst
limits or other limits
as to the maximum number of requests in a minute or other amount of time.
Drill allows you to
set a `retryDelay` parameter which is the number of milliseconds that Drill
should wait before
resending the request. This defaults to 1 second. This option is set in
the configuration for
the HTTP plugin.
## Testing
Added unit test.
