Opher Shachar updated NIFI-7809:
--------------------------------
Description:
The documentation for "File Filter Regex" property of ListSFTP processor reads:
{quote}Provides a Java Regular Expression for filtering Filenames; if a filter
is supplied, only files whose names match that Regular Expression will be
fetched
{quote}
But it should be made clear that the Regex *_needs_* to match the _*whole*_
filename. e.g. to filter files ending in ".txt.gz" the following will not work:
{code:java}
\.txt\.gz$
{code}
You'd need to specify:
{code:java}
.*\.txt\.gz
{code}
or equally:
{code:java}
.*\.txt\.gz$
{code}
