Integrating Tika with Apache Beam
Hi Tim, All,
I thought I'd start a dedicated thread.
I added some initial comments to [1], I'm quite close now to creating
the initial PR.
Thanks, Sergey

Hi Tim
I just used 'mvn install -DskipTests=true' to quickly build it, and did
'mvn clean install' inside the tika module.
I use Eclipse, Beam docs on how to set up it are good, except that it
did not quite work for me yet for all of Beam, only managed to import
the individual Tika module
Cheers, Sergey

Hi Tim
Thanks, the code, especially the one dealing with adapting the Tika
events to the Bean pipeline will most likely need to be improved :-),
I've tried to make sure it all can be configured as much as possible
(point to the loc of the TikaConfig if needed, etc), but it's only a
start...
I already see a typo in the TikaOptions doc for the minimum text length,
time to create a new PR :-)

Are these data the 'metadata' (author, date) or the text content ? The
main issue so far is that TikaIO will extract the content in the right
order but the Bean threads can totally reorder the individual content
pieces - so the first question is what, from the practical point of
view, can be done with these unordered data pieces, and then the follow,
TikaIO+Beam implementation specific issue, is how to ensure the data are
ordered all the way, till they reach the end of the pipeline
I'll CC you :-)

Re: Integrating Tika with Apache Beam
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi All
A short update that my original TikaIO contribution changed a lot after
the round of reviews, but the good news it stayed as a native Beam IO
component and will be available from Beam 2.3.0.
TikaIO will now return something called ParseResult which includes the
complete String and metadata content, but also Throwable if the
exception occurred in some file.
Tika Streaming is not utilized at the moment - but as soon as the good
use cases emerge then I'm sure Beam community will be open to enhancing
TikaIO further...
Cheers. Sergey

Re: Integrating Tika with Apache Beam
Posted by Chris Mattmann <ma...@apache.org>.
Thanks Sergey, feel free to CC me directly at mattmann@apache.org on the Beam thread.
My own 2c is that Tika’s “metadata” extraction can be any order, and with our tika-dl module
and the new feature extraction from multimedia files using Tensorflow and DL4j these are
perfect examples where the order/extraction doesn’t matter…

Hi Guys
TikaIO is getting some serious attention now on the Beam dev, and
unfortunately it is not all about it being a great addition to Beam.
The team is wondering what one can do with TikaIO vs someone just doing
some custom Beam function.
TikaIO and as any other Bounded text reader will produce the data in the
ordered way, but they can be made totally unordered to the pipeline by
the Beam runtime.
I gave one example where we used the Tika output to save it all to
Lucene (with the file name associated) and then search for the files
which contain a certain word.
Tim, Chris, others, if you have some interesting examples to share where
it did not matter in which order Tika-produced data were made eventually
available, then please let me know, or reply directly to a Beam dev
thread titled "TikaIO concerns".
Note, if Beam devs decide they don't want it then one option can be to
create a tika-integrations/beam module and experiment there - I'm not
saying it will need to be done but it's something that may be worth
considering

Re: Integrating Tika with Apache Beam
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi Tim
Thanks, will link you to the thread shortly
In general, I'd say TikaIO has probably generated more interest then
some of the other Beam IOs which is a good sign :-)
The questions at the moment:
1) what interesting things can be done with the unordered Tika produced data
2) would it really help if users can write the custom functions
themselves (I'd say the utility code always helps for some cases)
I also believe it would be possible to somehow make all the Tika
produced data ordered in the end, but that would be the next phase...
At the moment it's those 2 issues which are the main ones...
Thanks, Sergey
P.S I'd not like this TikaIO idea to cause some 'battles' :-), I think
it would be cool if Tika were one of the native Beam IOs (it would also
be big for the tooling side of things), if not then indeed Tika users
can easily do something themselves on top of Beam

Re: Integrating Tika with Apache Beam
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi Guys
TikaIO is getting some serious attention now on the Beam dev, and
unfortunately it is not all about it being a great addition to Beam.
The team is wondering what one can do with TikaIO vs someone just doing
some custom Beam function.
TikaIO and as any other Bounded text reader will produce the data in the
ordered way, but they can be made totally unordered to the pipeline by
the Beam runtime.
I gave one example where we used the Tika output to save it all to
Lucene (with the file name associated) and then search for the files
which contain a certain word.
Tim, Chris, others, if you have some interesting examples to share where
it did not matter in which order Tika-produced data were made eventually
available, then please let me know, or reply directly to a Beam dev
thread titled "TikaIO concerns".
Note, if Beam devs decide they don't want it then one option can be to
create a tika-integrations/beam module and experiment there - I'm not
saying it will need to be done but it's something that may be worth
considering

Re: Integrating Tika with Apache Beam

Hi Chris
thanks,
at the moment TikaIO (originally renamed TikaReader as it can only read
but we renamed it to follow the convention) is a bounded reader, so you
can say ask it to read
/files/*.pdf
and it will read all the N files there, and will end the run.
I'm not sure yet what is the best strategy to making it the unbounded
reader where it can continuously poll or be notified of the new files
becoming available...There are some ideas about scheduling the bounded
Beam pipelines, haven't looked yet...
In the short term, the simplest solution would be simply to create a new
instance of TikaIO pipeline, and point it to the new temp folder where a
new batch of files has been dropped to.
Thanks, Sergey

Re: Integrating Tika with Apache Beam

Hi Tim, All
It took it some time, but finally Beam TikaIO component is in its
2.2.0-SNAPSHOT master,
https://github.com/apache/beam/tree/master/sdks/java/io/tika
I've created a basic project which can help with running it quickly:
https://github.com/sberyozkin/beamTikaExample
One can just build it and run as suggested in Readme.md, simply have
some PDF files for example, and point to one or all of them.
By default, Beam will output the data to /tmp/tika.
main() can be updated with supporting more options, they can be
collected from the command line either with TikaOptions:
https://github.com/apache/beam/blob/master/sdks/java/io/tika/src/main/java/org/apache/beam/sdk/io/tika/TikaOptions.java
(all options but the "--input" are optional)
or directly from the code, some variations are shown in the tests:
https://github.com/apache/beam/blob/master/sdks/java/io/tika/src/test/java/org/apache/beam/sdk/io/tika/TikaIOTest.java
By default TikaReader will use an internal queue to make the SAX events
available to the Beam pipeline, this is why you can see the options like
"queuePollTime", etc. If it's known that a given parser can really read
the whole text in the single op only then the process can be optimized
with 'parseSynchronously'...
One can also try to update main() in the example to do more interesting
things then just print the data :-).
Give it a try please if you get a chance, help make TikeIO the major
part of Beam :-) with PRs, etc
