New Replica Types in Solr 7 #bbuzz
summary
Solr 7 adds three replica types so clusters can trade immediacy for availability: NRT replicas index and write the tlog and support soft commits and real‑time gets; TLOG replicas write the tlog but defer indexing and apply segments periodically, enabling fast writes without immediate searchability; PULL replicas neither receive live updates nor become leaders but periodically pull full segments, remaining active during leader‑initiated recovery. Combinations enable a Master/Slave‑like setup with automatic leader election, replica placement via autoscaling, query routing preferences, and reduced recovery load.
