----------------------------------------
Summary: GEOMETRY gaps: Think through client interface
Key: IMPALA-15244
URL: https://issues.apache.org/jira/browse/IMPALA-15244
Project: IMPALA
Issue Type: Sub-task
Components: Backend, Clients
Reporter: Csaba Ringhofer
What type to return to clients is not a clear decision:
"dumb" clients without geo lib benefit from something readable, e.g. WKT
"smart" clients with geolib benefit from some binary protocol, e.g WKB
I prefer making this settable with a query option, for example see Snowflake's
approach:
https://docs.snowflake.com/en/sql-reference/data-types-geospatial :
GEOMETRY_OUTPUT_FORMAT/GEOGRAPHY_OUTPUT_FORMAT can switch between WKT, WKB,
etc..
psql uses hex encoded EWKB or binary EWKB in binary mode
