Timo Walther updated FLINK-18090:
---------------------------------
Description:
This updates the Row.toString method to provide a good summary string.
In particular it fixes the following issues:
Changeflag: According to FLIP-95, a row describes an entry in a
changelog. Therefore, it should visible whether a row is an insert,
delete, or update change. Now indicated with +I, -D, +U, -U.
Nested rows: In the old implementation it was not visible whether nested
rows exist or not due to missing start/end boundaries. Now indicated with
[...] or {...}.
Positioned rows vs. named rows: According to FLIP-136, it should be visible
whether a row operates in name-based or position-based field mode. Now
indicated with [...] or {...}.
Nested arrays in maps and lists: In the old implementation arrays in maps
or lists could not be represented.
Wrong formatting: Most programming languages use a space after a comma.

This is an incompatible change. If the legacy representation is still
required for tests, the old behavior can be restored via the flag
RowUtils.USE_LEGACY_TO_STRING for the local JVM. However, relying on
the row's string representation for tests is not a good idea in general as
field data types are not verified.
