I am looking for lessons learned or problems seen when building a Solr index
from AEM using a Solr cluster with content passing through an ELB.
Our configuration is AEM 6.1 indexing to a cluster of Solr servers running
version 4.7.1. When building an index with a smaller data set - 4 million
items, AEM sends the content in about 3 minutes and the index is built without
issue. When building an index for 14 million items, AEM sends the content in
about 9 minutes. The Solr server error log records errors of EofException. When
a single Solr server is used and the ELB bypassed, the index is built in about
1.75 hours with no errors.
Thanks for your comments and suggestions.
