Luís Filipe Nassif commented on TIKA-3221:
------------------------------------------
My 2 cents, in the past I had ConcurrrentModificationExceptions by metadata
being read by client thread, while timed out parsing threads eventually writes
to metadata. I "solved" with a try-catch block. IMHO, ConcurrentHashMap is lock
free, so Tim's conclusion about small overhead makes sense. I think using it
could be good.
But the best solution to handle timeouts is using ForkParser or tika server.
> /rmeta/text endpoint - allow a "max parse time" parameter where after

> Key: TIKA-3221
> URL: https://issues.apache.org/jira/browse/TIKA-3221
> Project: Tika
> Issue Type: Bug
> Reporter: Nicholas DiPiazza
> Priority: Major
>
> Can we make a change to the
> {code}
> /rmeta/text
> {code}
> endpoint to allow a "max parse time" parameter where after exceeded, return
> bytes/metadata managed to get up to that point.
> Motivation:
> I have a massive number of documents that I need to fetch through apache tika
> server.
> Prior to making a switch to tika server, I used a project I created myself
> https://github.com/nddipiazza/tika-fork that created tika forked VMs and
> would send work to the VMs through sockets directly.
> This was OK but super complicated so I chose to switch to the Tika jetty
> server for simplicity's sake.
> Tika Server works great for the most part for this use case... But one
> feature I had before was that I could say "If I don't get a result within
> MAX_PARSE_TIMEOUT_MS, then stop parsing at that moment and return the bytes
> we managed to get up to that point.
> This is because with the massive number of documents I need to parse, I
> cannot afford to have any parse hang longer than a certain amount of time.
> But conversely, if I make timeout 20 seconds, then I suffer massive gaps with
> *no* content at all.
> With the rmeta/text method, we recently added the ability to send a
> writeLimit where we will stop parsing after we reach that number of bytes.
> I'm hoping we can do the same for the time parsed. Perhaps when checking byte
> size, periodically check time and quit parser in the same way.
