[jira] [Commented] (IGNITE-11141) Add Java method to create a cache from a template

["Moldachev Sergey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-11141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16757028#comment-16757028 ] 

Moldachev Sergey commented on IGNITE-11141:
-------------------------------------------

[~slukyanov] The IgniteKernal has GridKernalContext ctx with cache() method which return GridCacheProcessor by which I can get the CacheConfig by template name. Could you please review a simple implementation?
{code:java}
CacheConfiguration ccfg = ctx.cache().getConfigFromTemplate(cacheName);
if (ccfg == null) {
     return cache(cacheName).getConfiguration(CacheConfiguration.class);
} else {
     return ccfg;
}
{code}

Thank you!

> Currently cache templates can only be used via REST or SQL: https://apacheignite.readme.io/docs/cache-template.
> It seems reasonable to add the same functionality to Java.
> The most flexible way would probably be to add a method like `cacheConfiguration(String)` that would return a configuration of a template with the given name. Then to create a cache from a template one would write code like this
> {code}
> CacheConfiguration cfg = ignite.cacheConfiguration("myTemplate");
> cfg.setName("myCacheFromTemplate");
> ignite.createCache(cfg);
> {code}
> As a bonus, the `cacheConfiguration(String)` method may work with regular caches too. For them it would be a shortcut for `ignite.cache("myCache").getConfiguration()`.
