-- Updates a campaign by either deploying a new solution or changing the
-- value of the campaign\'s @minProvisionedTPS@ parameter.
--
-- To update a campaign, the campaign status must be ACTIVE or CREATE
-- FAILED. Check the campaign status using the
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeCampaign.html DescribeCampaign>
-- operation.
--
-- You can still get recommendations from a campaign while an update is in
-- progress. The campaign will use the previous solution version and
-- campaign configuration to generate recommendations until the latest
-- campaign update status is @Active@.
--
-- For more information on campaigns, see
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_CreateCampaign.html CreateCampaign>.
