-------------------------------------------
[~qvad]
Currently, it's only possible to enable/disable cache which is a cache group
itself
In case we want to support such cases we should think twice os it ok to change
wal state for all caches iтышву group in case only one provided.
Also, is it ok to change wal state by group. How will we change the API?
Anyway,
Looks like we have to fix the following code to support the first case.
{noformat}
HashSet<String> grpCaches = new HashSet<>(grpDesc.caches().keySet());
grpCaches.removeAll(cacheNames);
if (!grpCaches.isEmpty()) {
return errorFuture("Cannot change WAL mode because not all cache names
belonging to the group are " +
"provided [group=" + grpDesc.groupName() + ", missingCaches=" + grpCaches +
']');
}
{noformat}
The second case can be supported by improving the following code to scan groups
too
{noformat}
for (String cacheName : cacheNames) {
DynamicCacheDescriptor cacheDesc = cacheProcessor().cacheDescriptor(cacheName);
if (cacheDesc == null)
return errorFuture("Cache doesn't exist: " + cacheName);
caches.put(cacheName, cacheDesc.deploymentId());
CacheGroupDescriptor curGrpDesc = cacheDesc.groupDescriptor();
{noformat}
see org.apache.ignite.internal.processors.cache.WalStateManager#init for
details.

> Following code doesn't work if cache is in a cacheGroup:
> {code:java}
> ignite.cluster().disableWal(cacheName){code}
> cacheName == cacheName:
> {code:java}
> Caused by: class org.apache.ignite.IgniteCheckedException: Cannot change WAL

> cache_group_3_062, cache_group_1_001, cache_group_1_002]]
> {code}
> cacheName == groupName:
> {code:java}
> Caused by: class org.apache.ignite.IgniteCheckedException: Cache doesn't

> Also there is no javadoc about this behaviour
