I was trying to follow this post:
https://crate.io/a/big-cluster-insights-ingesting/
But I’m not sure how to set:
memory.index_buffer_size: 25%bootstrap.mlockall: true
where can I find some documentation on this?
Hi,
You have read the article dated 2016-04-19 (four years ago), so now I am curious as to what may have changed since then. Having a look at the release history, I find that the nearest to that date is 0.54.8, see here.
Since then, there has been a rename of bootstrap.mlockall in version 2.0.0:
The node setting bootstrap.mlockall has been renamed to bootstrap.memory_lock
(searching for the property in the reference reveals this.)
To use the setting you need to configure it in your crate.yml configuration file.
Regarding indices.memory.index_buffer_size, that node level setting is not explicitly documented, but being part of CrateDB’s “persistence and consensus”-ware, elasticsearch, you should be able to override its value in crate.yml too.
Happy days!
