> Text extraction is sometimes slow, and, in case of a bug in the text extraction library,
can even get stuck in an endless loop.
> Right now, it is not easy to understand what is going on, even when looking at full thread
dumps. (Debug) log information about the current state of text extraction would be nice as
well.
> I suggest we add debug level logging for the current extracted binary (content identity).
For larger binaries, we can also temporarily set the thread name (append "Extracting <contentIdentity>").
That way, it is relatively easy to see if text extraction is stuck simply looking at full
thread dumps, without having to change the log level and then reindex.
