Cross Data Center Replication for the Enterprise
This presentation is meant to explore the use of cross data center replication, now available in Solr 6, to show a real-world example running in production. Iron Mountain has now been running cross data center replication (CDCR) for over a year. We have over 100,000 users and indexes supporting 26 clouds (5 billion documents) with rapid/continuous indexing. We rely on cross data center replication for disaster recovery and backups. This allows us to maintain a 'hot' standby environment for failover. We spent considerable effort performance testing and tuning CDCR as well as determining the hardware / storage required to support the system. There are some gotchas that need to be considered, such as the amount of disk space to allow for backups, network performance, adjusting configurations and monitoring.

CDCR works much like mirroring approaches for databases, yet there are some distinct differences in how this works for Solr. The implementation of CDCR was performed by several committers which Iron Mountain engaged to develop the capability. Representatives from the team will speak to the technical approach CDCR uses, the CdcrRequestHandler and versioning approach used.

Lastly, we will cover some possible future enhancements for CDCR, including improving throughput and extending the current code base to support active/active replication between multiple data centers.
