Summary

This function creates forests on specified hosts and forms a partition with the specified partition number. All of the forests will share the partition name as their prefix and the same partition number. The query for the partition is set separately by the tieredstorage:partition-set-query function.

Parameters
database-id	ID of the database in which the query partition will reside.
partition-name	Name of the query partition.
partition-number	The number of the query partition.
forests-per-host	Number of forests per host in the partition to be created.
host-ids	Ids of hosts on which to create the partition forests.
data-directory	The optional data directory of the forests. If no directory is specified, then the forests will be private.
large-data-directory	The optional directory where large objects are stored. If no directory is specified, then large objects will be stored in DATA_DIR/Forests/FOREST_NAME/Large.
fast-data-directory	The optional directory for the fast data directory for the forests. The fast data directory is typically located on a fast storage device, such as an SSD.
options	Valid option values include: failover =[none, local, shared] If failover is `local` and multiple hosts are specified, new replica(s) will be created. Shared disk failover will be set up if failover is `shared` and multiple hosts are specified. The failover hosts will be chosen to cover as many different zones as possible. If failover is `none`, neither will be set up. If failover is left unspecified, it will be `local` unless data directories are on shared platforms such as HDFS and S3. replicas=N Specifies the number of replicas/failover forests to configure for local-disk or shared-disk failover.

Example

// Creates a Query Partition, named "Default," identified as partition number 
// "1" and consisting of two forests for the "Documents" database.

const ts = require('/MarkLogic/tieredstorage');

declareUpdate();
ts.queryPartitionCreate(
   xdmp.database('Documents'),
   'Default',
   1,
   2,
   xdmp.host('host-1.marklogic.com')
);
