Page History

page_size=<n>

This is a CMR parameter to control the number of granules in the page of returned results. 

Discussion: When there are multiple granules returned from the CMR query, they are returned in sets called pages. The default page size is 10 granules. The page_size KVP allows the user to change the page size. Multi-page results can be accessed one page at a time using the page_num KVP described below. 

Note that the system configuration parameter MAX_GRANS_FOR_SYNC_REQUEST limits the size of a request in EGI. Exceeding that number returns an error. Page_size should always be set to less than or equal to this request limit.

See the FAQ for more discussion.
