Distributed LDAP Databases

Advantages of Distributed LDAP Databases

  • smaller databases make for simpler and faster backup and recovery
  • process size is smaller
  • process map traversal is faster
  • shorter pauses during Directory Server checkpoints
  • smaller databases can be housed on smaller hardware, maximizing rack space and power utilization
  • greater scalability: as the number of entries increases, distributed databases grow horizontally
  • capacity is more easily predicted in horizontally-scaled architectures

Overview of the Distribution Mechanism

  • support massively scalable deployments
  • [Sun Java System Directory Proxy Server] provides distribution mechanism
  • flat namespace distribution across set of directory servers with out of the box and programmable distribution algorithms
  • operation-based routing
  • load balancing
