Frank Greguska commented on SDAP-16:
------------------------------------
Was able to implement some basic xarray usage and time it against the original
using local data.
Non xarray:
735 ms ± 53.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
With xarray
980 ms ± 97.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
> Prototype multidimensional tiles

> URL: https://issues.apache.org/jira/browse/SDAP-16
> Project: Apache Science Data Analytics Platform
> Issue Type: Improvement
> Components: nexus
> Reporter: Frank Greguska
> Assignee: Frank Greguska
> Priority: Major
>
> The current representation of a tile in NEXUS is a flat 2-D grid indexed by
> latitude and longitude. This structure is proving to be insufficient for the
> heterogenous data NEXUS is required to handle.
> We need to experiment with n-dimensional tiles (in reality, 4 dimensions is
> probably the maximum: latitude, longitude, time, and depth/altitude) to see
> if we can improve functionality and performance of the system.
> This issue will track changes required to the system in order to handle
> n-dimensional tiles.
