Almost never. I would only run a re-index for newer versions (such as
6.5.2 to 7.2) that have a required feature or schema changes such as
changing the type of an existing field (int to string for example). Not
sure what you mean by 'every delta', but I would assume you just mean
new data? If so, then re-indexing is not necessary.

Hi Guys,
How often do I need to run full reindex on SolrCloud? It takes more than 12
hours for full reindex to run and we run it every night but is it really
necessary to do it as delta runs correctly.
New data comes in at the rate of 2000 documents on every delta per 30
seconds.
Total index size : 20GB Solr: 6.5.2
