Significance of Index atomic=true in SOLR ?

[deepak1987]

We know that by default, indexing for all properties are:

<index enabled="true">
         <atomic>true</atomic>
         <stored>false</stored>
         <tokenised>true</tokenised>
</index>
‍‍‍‍‍‍‍

Here, Atomic="true" means the property is indexed in the transaction. If not, the property is indexed in the background.

And SOLR does not perform in-transaction indexing. So, What is the significance for keeping default value for Atomic="true" ? ?

For Lucene, this atomic attribute is required but does it have any importance for SOLR ? ?

Hello,

no, it has no significance for SOLR. The default value is there to allow the continued use of Lucene with its old behavior as the search subsystem when customers / users do not want to or cannot switch to SOLR.
