-----------------------------------------
Summary: Split CSV adapter to simpler parts for better readability
Key: CALCITE-472
URL: https://issues.apache.org/jira/browse/CALCITE-472
Project: Calcite
Issue Type: Bug
Affects Versions: 1.0.0-incubating
Reporter: Vladimir Sitnikov
Assignee: Julian Hyde
It might be better to split adapter in different classes/packages/modules so
each feature is easily observable:
1) "Demonstration of CSV full scan"
2) "Demonstration of CSV table that returns just required columns"
3) "Demonstration of CSV filterable table"
4) "Demonstration of table that returns _MAP"
etc.
Currently lots of features are mixed in a single implementation, thus it is a
bit tricky to figure out how CsvSmart table differs from CsvDump table. Earlier
I somehow managed to get over it, however that was very confusing.
