Re: loading a cache into memory after startup

2019-06-19 Thread mahesh76private
I don't know if I even want to call an api to warm up memory. I am thinking, we could have a setting like the below in config xml, this is userfriendly and intention of the config file is very clear. Bottomline: if ignite is used more often from disk, then it loses its value from a performance sta

Denis, thanks for pointing out to that ticket. Reopened that ticket proposing to reconsider the public API: https://issues.apache.org/jira/browse/IGNITE-8873 Generally, I'm in doubts that IgniteCache.preloadPartition is the right API from the usability standpoint. For instance, Mahesh do you unde

Re: How to know memory used by a cache or a set

2019-06-19 Thread Alex Plehanov
Denis, Documentation for memory usage calculation covers another case (memory usage by the node). There is no ability (AFAIK) in released Ignite versions to calculate memory used by a cache or cache group when persistence is disabled. Dedicated data region can be used for some of the caches in som

Hi Taruk, There is no such thing out of box. You can try to use org.apache.ignite.Ignition#addListener and handle org.apache.ignite.IgniteState#STOPPED_ON_SEGMENTATION state change according to your needs. Perhaps, if you can describe why do you need a specific handling then the Community might s
