> Hi SOLR Experts,
>
> I am facing one challenge regarding performance in *Java Spring Boot +
> Apache Solr Cloud *based application.
>
> Details are as follows:
>
> *Data present in Solr collection*: 41 million
>
> *Shards:* 8
>
> *Replicas:* 2
>
> *Solr Version:* 8.2.0
>
> *Issue:* we are having export functionality based on filters applied by
> user on data, maximum export limit is 1 lakh records. It is taking more
> time than expected (approximately 10 min and even its not consistent.
> Sometimes in seconds and sometimes more than 8-10 min)
>
> *Limitation:*
>
> 1. Multi-threading cannot be used.
> 2. We are not allowed to pull more than 5000 records in one Solr call
> as this Solr instance is shared among other applications as well.
>
> But client is expecting more improvement in performance. Please let us
> know if you have any suggestion which can help improving performance in
> above case.
