Update Settings: new value of refresh_interval is not observed without restart (w/ Gist)

David_2 · March 22, 2012, 4:08pm

I've run into a problem that looks like a bug with 0.19.0 and 0.19.1.
I have a bulk index process that follows the suggested pattern of
setting refresh_interval to "-1" during the index and then changing it
back to "1s" after the index is done. With the 0.19.x versions, I've
noticed that the dynamically set values of refresh_interval, while
they seem to be changed in the settings, are not observed without a
restart.

See this gist for a series of commands that you can run on a vanilla
single instance of elastic that recreates this problem:

gist.github.com

https://gist.github.com/mackd/2159205

refresh_interval_problem.sh

# Run this on a completely vanilla, fresh instance of elasticsearch 0.19.x


# Create index with initial -1 refresh interval.
curl -XPUT 'http://localhost:9200/twitter/?pretty=true' -d '
index :
    refresh_interval: "-1"
'

# Update refresh interval using update settings to 1s.

Looks like a bug.

Looks like a bug.

Confirmed - refresh_interval seems to be ignored completely

Opened an issue: Index Update Settings API does not update settings in real time · Issue #1807 · elastic/elasticsearch · GitHub,
a fix is coming...
