[jira] [Updated] (FLINK-5714) Use a builder pattern for creating
CsvTableSource
[ https://issues.apache.org/jira/browse/FLINK-5714?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Timo Walther updated FLINK-5714:
--------------------------------
Description:
Right now, the constructor of the CsvTableSource can have up to 9 parameters. In Scala this might not be a problem because of default values, but Java doesn't have this functionality.
I propose to have a a builder pattern here:
{code}
CsvTableSource
.builder()
.field("myfield", Types.STRING)
.field("myfield2", Types.INT)
.quoteCharacter(';')
.build()
{code}
