collection_rebalanceleaders: Rebalance leaders

In solrium: General Purpose R Interface to 'Solr'

Description

Reassign leaders in a collection according to the preferredLeader property across active nodes

Usage

collection_rebalanceleaders(
  conn,
  name,
  maxAtOnce = NULL,
  maxWaitSeconds = NULL,
  raw = FALSE,
  ...
)

Arguments

conn	A solrium connection object, see SolrClient
name	(character) The name of the core to be created. Required
maxAtOnce	(integer) The maximum number of reassignments to have queue up at once. Values <=0 are use the default value Integer.MAX_VALUE. When this number is reached, the process waits for one or more leaders to be successfully assigned before adding more to the queue.
maxWaitSeconds	(integer) Timeout value when waiting for leaders to be reassigned. NOTE: if maxAtOnce is less than the number of reassignments that will take place, this is the maximum interval that any single wait for at least one reassignment. For example, if 10 reassignments are to take place and maxAtOnce is 1 and maxWaitSeconds is 60, the upper bound on the time that the command may wait is 10 minutes. Default: 60
raw	(logical) If TRUE, returns raw data
...	You can pass in parameters like property.name=value to set core property name to value. See the section Defining core.properties for details on supported properties and values. (https://lucene.apache.org/solr/guide/8_2/defining-core-properties.html)
