Change index.cache.field.type on live index

bohemer_2 · December 11, 2012, 2:03pm

I have a large index with around 70M documents and in the mapping is
specified that the index cache type is soft. Is there a way to change to
index.cache.field.type setting from soft to resident without to reindex the
index?

I'm not sure, but I think you should be able to update this setting
via the update indices settings api and then restart the nodes.
When the index is being loaded on a node during startup, the updated
settings should be picked up.

Another approach which might be easier, is after you have changed the
settings to close and then open the index. This way
you don't need to restart any node.

Unfortunately this setting can can't be changed during the time an
index is live.

Hi,

Thank you Martijn for the quick response,

I have updated the index settings on a development instance to
index.cache.field.type = resident. the response was {"ok":true} so it
should work. Then i closed and then opened the index , but the get index
setting api call tells me that the cach type is still soft

Any idea how should i change the index cache type without to reindex all
the data ?

Thank You.

Non dynamic index properties can be updated, but the index needs to be
closed before updating the property. Like this:

gist.github.com

https://gist.github.com/martijnvg/8285c42729f8a54c5fae

update-non-dynamic-property-example.sh

curl -XDELETE 'localhost:9200/indexname?pretty'
#Creating an index with the non dynamic property: 'index.cache.field.type'
curl -XPUT 'localhost:9200/indexname?pretty' -d '{
	"settings" : {
		"index.cache.field.type" : "soft"	
	}
}'
curl -XGET 'localhost:9200/indexname/_settings?pretty'

# Closing an open index, to allow non dynamic properties to be changed.
