Hi Boris

 

Thanks a lot for this useful information. I assume that with the mentioned dev version this parameter will be accessible for the API user.

 

Regards from Switzerland,

Tony

Hi Tony,

 

We do have already the functionality of storing temp files (or rather decoded chunks of data) in memory up to a certain limit, and moving them to the temp files above this limit.

 

At the moment the limit is quite low (10K or so) and is a constant in the code. We’ll open this parameter to the library configuration, so that the user would be able to control this.

 

Best regards,

Boris

Hi Boris

 

Thanks a lot for your message and your offer!

We definitely appreciate a dev version and we therefore also will feed back our test results.

Please take in account that temp. files in my opinion are problematic for thread safeness. On the other hand big pdfs are problematic for memory consumption. Therefore it was perfect, if one can configure the veraPDF validation engine whether one would have seamless validation by streams (without creation of temp. files) or if one would like to reduce memory usage and therefore allow temp files. Anyway, the temp folder should be configurable in order to respect access right policies (i.e. when used on servers).

 

Kind regards,

Tony

Dear Tony,

 

The performance and the memory optimization are our primary targets this and the next release. The coming release (1.10) will include a lot of memory optimization and significantly better performance in case of large test documents.

 

Thread-safeness is in the plans for the next release expected in first quarter of 2018. But if you are interested, we would be able to provide the dev version for tests a bit earlier (end of December or beginning of January).

 

Best regards,

Boris

Betreff: veraPDF and thread-safeness?

 

Hi

 

We have integrated veraPDF validation-model 1.8.1 from the maven repo (https://mvnrepository.com/artifact/org.verapdf/validation-model) into the eHealth Connector Open Source project (see https://sourceforge.net/projects/ehealthconnector/). See https://sourceforge.net/p/ehealthconnector/wiki/CDA%20Validation/ for more information.

 

The eHealth Connector supports multithreading, but veraPDF seems not currently to be thread-safe.

Is there any plan for a thread-safe veraPDF validation-model?

 

Thanks in advance for any response.

 

Regards, Tony
