Major Description
See the method code:
@Nullable public DynamicCacheDescriptor cacheDescriptor(int cacheId) {
for (DynamicCacheDescriptor cacheDesc : cacheDescriptors().values()) {
CacheConfiguration ccfg = cacheDesc.cacheConfiguration();
assert ccfg != null : cacheDesc;
if (CU.cacheId(ccfg.getName()) == cacheId)
return cacheDesc;
}
return null;
}
This method is invoked in several hot paths which causes significant performance regression when the number of caches is large, for example, logical recovery and security check for indexing.
The method should be improved to use a hash map or similar data structure to get a better complexity
