Increased Limits
Bucket Assignment Policy
In versions prior to MarkLogic 11.2, the bucket database assignment policy is limited to 1024 forests. In order to provide more flexibility for systems that are reaching that hard limit but need more headroom before they can change cluster topologies, starting with MarkLogic 11.2, that limit is increased to 2048 forests.
Important
Note that, though the hard limit for the bucket assignment policy was increased above 1024, the general recommendation that the total number of forests should not grow beyond 1024 per cluster remains in effect. If a cluster is approaching 1024 forests, it is recommended to explore the use of Super Databases and Clusters to divide the cluster into smaller subclusters.
Database Replication for Large Clusters
In versions prior to MarkLogic 11.2, database replication cannot be configured for databases that have forests on more than 256 hosts combined between the primary and the replica databases. E.g. configuring database replication for a database with 130 hosts in the primary cluster replicating to 130 hosts in a secondary cluster will fail. MarkLogic 11.2 increases that maximum to 512 hosts combined. This allows two clusters with up to 256 hosts each to be coupled for database replication.
