Try "stemEnglishPossessive" to remove.

Re: Data Import

[vishal jain]

Streaming the data through kafka would be a good option if near real time
data indexing is the key requirement.
In our application the RDBMS data is populated by an ETL job periodically
so we don't need real time data indexing for now.

Cheers,
Vishal

Re: Data Import

[vishal jain]

Thanks to all of you for the valuable inputs.
Being on J2ee platform I also felt using solrJ in a multi threaded
environment would be a better choice to index RDBMS data into SolrCloud.
I will try with a scheduler triggered micro service to do the job using
SolrJ.

Vishal

Data Import

[vishal jain]

Hi,


I am new to Solr and am trying to move data from my RDBMS to Solr. I know
the available options are:
1) Post Tool
2) DIH
3) SolrJ (as ours is a J2EE application).

I want to know what is the recommended way for Data import in production
environment.
Will sending data via SolrJ in batches be faster than posting a csv using
POST tool?


Thanks,
Vishal
