4. HA Cluster: Performance & features
• ClientAPI; Improved Sync Tx Log; Failover
• 2x faster writes compared to 5.4 (LDBC-50m)
• Tests: functional, stress, load. Extensible, open
• LVM-based backup & replication
• Plans:
– incremental backup
– Rsync-like full replication
– Integration with Connectors

9. Explain plan
• Explain plan – “FROM onto:explain”
• http://owlim.ontotext.com/display/GraphDB6/Graph
DB-SE+Explain+Plan
• Issues:
– No subquery support
– Queries are actually executed; long-running queries are a pain
• Explain plan lite – won’t show the execution times
