How is maxMemorySize calculated in the presence of backups?
For example, if I have an LruEvictionPolicy on a cache with one backup, and I say the maxMemorySize is 1G, will it evict when the primary has 1G or when the primary and the backup together have 1G? -- *JOSH CUMMINGS* Principal Engineer [image: Workfront] <https://www.workfront.com/> *O* 801.477.1234 | *M* 8015562751 joshcummi...@workfront.com | www.workfront.com Address <https://www.workfront.com/contact-us/> | Twitter <http://twitter.com/Workfront_Inc> | LinkedIn <http://www.linkedin.com/company/48453> | Facebook <http://www.facebook.com/workfront> [image: Workfront] <https://www.workfront.com/email-promo>
Re: Getting a cluster-configured JCache CacheManager instance
Here is what I did to satisfy our requirement:
System.setProperty("ignite.zookeeper.host",
resolvePropertyFromCentralizedRepo);
Caching.getCachingProvider(...).getCacheManager(springCfgUrl,
someClassLoader, someProps);
And then use the PropertyPlaceholderConfigurer and a placeholder in the xml
as you suggested.

Re: Getting a cluster-configured JCache CacheManager instance
Okay, thanks, I'll try that. Along similar lines, is there a way for me to
bring up an Ignite client, say programmatically, give it a name, and then
send just the grid name through the JCache API?
Not trying to make Ignite behave just like Hazelcast, but just to make my
thoughts clear with an example, there I can do this:
Properties properties = new Properties();
properties.setProperty("hazelcast.instance.name", "my-instance-name");
Caching.getCachingProvider().getCacheManager(someUri, someClassLoader,
properties);
And it will pick up a client I've already configured elsewhere in the
runtime by the name of "my-instance-name".
Is there a way to identify an already configured client through the JCache
API?
Thanks, again.

Getting a cluster-configured JCache CacheManager instance
I would like to get an instance of a JCache CacheManager that is configured to point at a remote Ignite cluster. I understand that I can provide a location to a spring configuration file with the correct discovery strategy, etc.; however, it appears that in that strategy I must supply an IP address directly in the file. All our configuration is housed centrally, so I cannot provide the IP address directly in the file. 1. What options are there for doing property placeholder resolution in the XML file? 2. What options are there for combining XML and java config in such a way that when I call Caching.getCachingProvider(...).getCacheManager(...), I get a cache that is the result of both XML and java config? (We are also evaluating Hazelcast and were able to get things working there over JCache using this approach.) -- *JOSH CUMMINGS* Principal Engineer [image: Workfront] <https://www.workfront.com/> *O* 801.477.1234 | *M* 8015562751 joshcummi...@workfront.com | www.workfront.com Address <https://www.workfront.com/contact-us/> | Twitter <http://twitter.com/Workfront_Inc> | LinkedIn <http://www.linkedin.com/company/48453> | Facebook <http://www.facebook.com/workfront> [image: Workfront] <https://www.workfront.com/email-promo>
Custom (de)serialization for a single field
I have an object I need to cache which has more than 100 fields. One particular field needs some custom handling when being (de)serialized. I've considered implementing Binarylizable; however, I don't care to manage all of the fields via the read and write binary methods. Where should I look in the api to configure custom (de)serialization for a single field? -- *JOSH CUMMINGS* Principal Engineer [image: Workfront] <https://www.workfront.com/> *O* 801.477.1234 | *M* 8015562751 joshcummi...@workfront.com | www.workfront.com Address <https://www.workfront.com/contact-us/> | Twitter <http://twitter.com/Workfront_Inc> | LinkedIn <http://www.linkedin.com/company/48453> | Facebook <http://www.facebook.com/workfront> [image: Workfront] <https://www.workfront.com/email-promo>
Dynamic caches over JCache
I am trying to do the following:
CacheManager cm = Caching.getCachingProvider().getCacheManager();
Cache cache = cm.getCache("my-cache");
At this point, cm points to an instance of
org.apache.ignite.cache.CacheManager and cache points to null.
I figured that Ignite would simply create the cache dynamically, but it
appears that CacheManager#getCache calls ignite.cache instead of
ignite.getOrCreateCache.
What is the correct way to use JCache and dynamically create a cache?
