As discussed here, we need to explore alternatives to blazegraph to scale WDQS. This requires free experimentation, and testing of the scalability itself (so requires multiple nodes). Discussion with @bd808 indicates that we should be able to have dedicated servers on WMCS which would provide adequate resources and isolation.
Ideally 3 servers with the following specs would be needed (limited validation of a solution would be possible with 2 servers).
Specs:
- 8 cores
- 128G RAM
- 3T usable SSD storage (probably 6T RAID1)
- 1G NIC
