Re: Transactions behaviour on Batch insert / update

Hello Ganesh,
By default the half of batch fails.
https://lucene.apache.org/solr/6_2_1/solr-core/org/apache/solr/update/processor/TolerantUpdateProcessorFactory.html
can fail only certain problematic rows. FWIW, you can send delete for
uncommitted documents, it wipes them from ram buffer, that's how you can
rollback a failed batch.

Transactions behaviour on Batch insert / update

[Ganesh M]

Hi all,

We are planning to make use of batch update / insert of solr documents, with 
batch size of around 100 documents per batch.

Bit curious on how transactions are maintained per batch. I do knew SOLR is not 
meant for transaction based, but want to know whether SOLR is designed to throw 
error even if one document in batch fails due to issue in data or invalid 
fields.

In case of such errors, whether complete batch fails or only one specific 
document fails and we get error for that specific document.

Pls let me know how SOLR behaves.

Regards,
Ganesh
