Hi Kevin,

Normally restarted Ignite node will pull data from other nodes. We call this process "rebalance".

Also Ignite comes with a special store type - local store (see @CacheLocalStore annotation). Local store could be used to re-load node's data after restart. However, Ignite doesn't have any local store implementations. You can find one in some Ignite-based commercial products, such as GridGain.

Hi Val,
When the exception occurred, I checked the forum and reset the java vm size to 30g, and also I split my table into 10 smaller tables, each contains 1g data.
In this case, I saw your suggestion on off-heap settings. I don't want to reload all the data again, So I asked if it is possible to make the configuration take effect immediately at running time.

Btw, I see there are backup settings in partition mode,    like this  <property name="backups" value="1"/>
But I did not see where those backups are stored. Is there any settings like redis which will automatically load dump files when redis recovered from an accident?

Regards,
Kevin

主题: Re: re: ignite problem when loading large amount of data into cache

Kevin,

Configuration of the existing cache can't be changed in runtime. The only option is to destroy the cache and create it again with new parameters (you will lose all in-memory data, of course). What's the use case when you can need this?
