What is mean of the page_size for CREATE TABLE?


#1

Hi mapd experts,

When I create a table, I can assign some properties to change the mapd storage behavior, such as fragment_size, max_rows, page_size. The online document introduce these peroperties. But I still don’t understand the page_size. Why mapd need to read data from disk page by page? Does it affect mapd’s performance?

Thanks,
Mike

Hi @mikedimsf,

Currently page_size shouldn’t have any effect at this point and can be left at the default. In the future that parameter may have an affect at the granularity with which in-memory updates are handled.
