Hi Ganesh, In general it shouldn't be an issue if you execute sum queries every other hour but you may want to share your cluster configuration (solr version, solr cloud?, # machines, machine configuration, index size) and load(indexing & query load) and perform some tests.
Also FYI, there is streaming/sql functionality available in latest Solr (6.0 above) which are capable of performing these aggregations etc. in parallel(map-reduce way).
