How Suffix Initialization Uses Cache
Chapter 6 Tuning Cache Sizes 117
Figure 6-4 Suffix Initialization (Bulk Loading) and Cache
To initialize a suffix, Directory Server:
1. Starts a thread to feed an entry cache, used as a buffer, from LDIF.
2. Starts a thread for each index affected and a thread to create entries in the
import cache. These threads consume entries fed into the entry cache.
