Juliusz Sompolski commented on SPARK-29349:
-------------------------------------------
[~runzhiwang] it is used by Simba Spark ODBC driver to recover after a
connection failure during fetching when AutoReconnect=1. It is available in
Simba Spark ODBC driver v2.6.10 - I believe it is used only to recover the
cursor position after reconnecting, not as a user facing feature to allow
fetching backwards.
