Re: In Place Updates not work as expected

[mganeshs <mg...@live.in>]

Hi Emir,

I am using solrj to update the document. Is there any spl API to be used for
in place Updates ? 

Yes are we are updating in Batch of 1000 documents. 

As I mentioned before, since I am updating only docvalues i expect it should
update in faster than updating normal field. Isn't it ?

Regards,

Hi,
That’s how you build regular document. Incremental/atomic updates need to use update commands. 
Did not check latest Solrj, so maybe there is built in way of doing that, but quick googling showed how it can be achieved:

 SolrInputDocument doc2 = new SolrInputDocument();
    Map<String,String> fpValue2 = new HashMap<String, String>();
    fpValue2.put("add","fp2");        
    doc2.setField("FACTURES_PRODUIT", fpValue2);
HTH,
Emir

Hi Emir,

It's normal setfield and addDocument

for ex.
in a for loop 
   solrInputDocument.setField(sFieldId, fieldValue);
and after this, we add the created document.
   solrClient.add(collectionName, solrInputDocuments);

I just want to know whether, we need to do something specific for in-place
updates ? 

Kindly let me know,

Regards,

Hi,
Can you share part of code where you prepare update.

Thanks,
Emir

Maybe.  But not always.

To do an in-place update, Solr must rewrite the docValues data for that 
field in that segment.  It must write this data for *EVERY* document in 
that segment which has that field.

If the segment has a few documents, this will almost certainly be very 
fast.  But if the segment with the document you are updating is large 
and contains enough documents that there are a million unique values for 
that field, then Solr is going to have to gather those million values 
from the existing data, then write a new file containing a million 
values.  This isn't going to be fast ... and a standard update probably 
would be faster.

Segments are part of the organization of a Lucene index.  Solr is a 
Lucene application.

Thanks,
Shawn
