core_swap

Swap a core

Description

SWAP atomically swaps the names used to access two existing Solr cores. This can be used to swap new content into production. The prior core remains available and can be swapped back, if necessary. Each core will be known by the name of the other, after the swap

Usage

core_swap(conn, name, other, async = NULL, raw = FALSE,
  callopts = list())

Arguments

`conn`	A solrium connection object, see SolrClient
`name`	(character) The name of the core to be created. Required
`other`	(character) The name of one of the cores to be swapped. Required.
`async`	(character) Request ID to track this action which will be processed asynchronously
`raw`	(logical) If `TRUE`, returns raw data
`callopts`	curl options passed on to crul::HttpClient

Details

Do not use core_swap with a SolrCloud node. It is not supported and can result in the core being unusable. We'll try to stop you if you try.

Examples

## Not run: 
# start Solr with Schemaless mode via the schemaless eg:
#   bin/solr start -e schemaless
# you can create a new core like: bin/solr create -c corename
# where <corename> is the name for your core - or creaate as below

# connect
(conn <- SolrClient$new())

# Swap a core
## First, create two cores
conn$core_create("swapcoretest1")
# - or create on CLI: bin/solr create -c swapcoretest1
conn$core_create("swapcoretest2")
# - or create on CLI: bin/solr create -c swapcoretest2

## check status
conn$core_status("swapcoretest1", FALSE)
conn$core_status("swapcoretest2", FALSE)

## swap core
conn$core_swap("swapcoretest1", "swapcoretest2")

## check status again
conn$core_status("swapcoretest1", FALSE)
conn$core_status("swapcoretest2", FALSE)

## End(Not run)
