Rama, while specifying DataFrame metadata length is good approach, can we
please have dbStringMappingType and dbStringMappingLength as properties on the
connection url as well? It will make it really easy for developers, as opposed
to dealing with dataframe length.
We have it implemented for IBM data servers, trying to see if we can make
it mainline Spark since its a useful feature.
VARCHAR has its limitations on length, hence under many circumstances,
users may want to map StringType to CLOB of varying lengths if data server
supports.
Let me know if we can pursue - we have the code ready.
Thanks.
Pallavi
