is the SolrJ call to add collection of documents a blocking function call ?

[ra...@thomsonreuters.com]

Hi:
   I am trying to index a collection of SolrInputDocs to a Solr server. I was wondering if the call I make to add the documents (the add(Collection<SolrInputDocument>)  call ) is a blocking function call ?

I would also like to know if the add call is a call that would take longer for a larger collection of documents


Thanks

Ramdev

Also consider StreamingUpdateSolrServer if you want multiple threads
to operate from your client.

Hi Ramdev,

add() is a blocking call. Otherwise it had to start an own background 
thread which is not what a library like Solrj should do (how many 
threads at most? At which priority? Which thread group? How long keep 
them pooled?)

And, additionally, you might want to know whether the transmission was 
successful, or whether your guinea pig has eaten the network cable just 
in the middle of the transmission.

But it's easy to write your own background task that adds your documents 
to the Solr server. Using Java's ExecutionService class, this is done 
within two minutes.

Greetings,
Kuli
