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.
