David Albrecht updated IGNITE-3864:
-----------------------------------
Description:
Decreasing the maxMemory Size of the SortedEvicitionPolicy using
SortedEvicitionPolicy#setMaxMemorySize(long) during runtime results in an empty
cache after another entry is put into cache.
Tested with the following scenario (see also attached screenshot):
# Initizalize SortedEvicitionPolicy with
{code}SortedEvictionPolicy evictionPolicy = new
SortedEvictionPolicy<>(5000000);{code}
# Set {code}evictionPolicy.setMaxMemorySize(2000000){code}
# Put 10000 entries into cache.
# Set {code}evictionPolicy.setMaxMemorySize(1000000){code}
# Put another entry into cache.
-> All cache entries are evicted -> 0 entries are in cache.
Since the method SortedEvictionPolicy.setMaxMemorySize(long) is also exposed
via the mbean I would expect that decreasing the max memory size should work
during runtime. (Increasing the max memory size works)
In addition you can see that the CurrentMemory Size read from the
SortedEvictionPolicy mbean via getCurrentMemorySize doesn't change after
decreasing the max memory size. Even after all cache entries are evicted and
the cache is complety empty
