@ -544,15 +544,14 @@ H3: Delta-syncrepl replication
OpenLDAP's syncrepl replication is an object-based replication mechanism.
When any attribute value in a replicated object is changed on the provider,
each consumer fetches and processes the complete changed object {B:both changed and unchanged attribute values}
during replication. This works well, but has drawbacks in some situations.
each consumer fetches and processes the complete changed object {{B:both changed and unchanged attribute values}} during replication. This works well, but has drawbacks in some situations.
For example, suppose you have a database consisting of 100,000 objects of 1 KB
each. Further, suppose you routinely run a batch job to change the value of
a single two-byte attribute value that appears in each of the 100,000 objects
on the master. Not counting LDAP and TCP/IP protocol overhead, each time you
run this job each consumer will transfer and process {B:1 GB} of data to process
{B:200KB of changes! }
run this job each consumer will transfer and process {{B:1 GB}} of data to process
{{B:200KB of changes!}}
99.98% of the data that is transmitted and processed in a case like this will
be redundant, since it represents values that did not change. This is a waste
