------------------------------------------
Summary: ContextualTextIO - An IO that is provides metadata about
the line.
Key: BEAM-10124
URL: https://issues.apache.org/jira/browse/BEAM-10124
Project: Beam
Issue Type: New Feature
Components: io-ideas
Reporter: Reza ardeshir rokni
There are two important Source IO's that allow for dealing with text files
FileIO and TextIO. When the requirements go beyond the scope of TextIO we ask
the end user to make use of FileIO and go it on their own.
We want to correct this experience by creating a more feature rich TextIO which
can return along with each line of data contextual information about the line.
For example the file that it came from, and the ordinal position of the line
within the file.
Another area that we would like to deal with is more formal support for CSV
files by allowing compliance to RFC4180 files. Specifically the RFC allows for
line breaks (CRLF) to be used within fields within double quotes.
