Dawid Wysakowicz updated FLINK-12799:
-------------------------------------
Description:
We should improve the extraction of {{TableSchema}} from
{{DataStream/DataSet}}. Currently it is split into a few stages:
# Extract types ignoring time attributes via {{FieldInfoUtils#getFieldInfo}}
# Extract the rowtime and proctime positions via
{{StreamTableEnvImpl#validateAndExtractTimeAttributes}}
# Adjust the indices from #1 using information from #2
All that could happen in a single pass. This will also deal with the
porting/removing of a few methods from {{StreamTableEnvImpl}}.
