[jira] [Created] (SDAP-349) Inefficient swath tile causes memory issues

Stepheny Perez created SDAP-349:
-----------------------------------

             Summary: Inefficient swath tile causes memory issues
                 Key: SDAP-349
                 URL: https://issues.apache.org/jira/browse/SDAP-349
             Project: Apache Science Data Analytics Platform
          Issue Type: Improvement
          Components: nexus
            Reporter: Stepheny Perez


In SDAP, swath data is stored in a horizontal along an nd matrix. For example, if lat,lon,time,data are size 30x30 for a swath tile, the result Tile constructed for computation in SDAP is 900x900x900 where the entire matrix is masked except for the diagonal where the data is populated. 

 

This might be due to outdated logic and how swath tiles were stored in previous versions of the SDAP ingester. More investigation is required.
