title: One big datasets or various subdatasets Jasper studio
body: <p>I am making a report that requires a complex query, the report has about 50 pages, and each page consists of a header and a table with around 30 rows.</p>
  
  <p>The question is whether I should create a single dataset (Sql), even if you repeat the header information for each record, or is it better to create a dataset for the headers and a table to see the records of each header?</p>
  
  <p>Which of the two options is more optimal?</p>
