%% OpenSearch Serverless is an on-demand, pre-provisioned serverless
%% configuration for Amazon OpenSearch Service. OpenSearch Serverless removes
%% the operational complexities of provisioning, configuring, and tuning your
%% OpenSearch clusters. It enables you to easily search and analyze petabytes
%% of data without having to worry about the underlying infrastructure and
%% data management.
%%
