      <section><p>Eviction policy based on First In First Out (FIFO) algorithm with batch eviction support.
<p>
The eviction starts in the following cases: 
The cache size becomes <a class="xref" href="Apache.Ignite.Core.Cache.Eviction.EvictionPolicyBase.html#Apache_Ignite_Core_Cache_Eviction_EvictionPolicyBase_BatchSize">BatchSize</a>
elements greater than the maximum size;
The size of cache entries in bytes becomes greater than the maximum memory size;
The size of cache entry calculates as sum of key size and value size.
<p>
Note: Batch eviction is enabled only if maximum memory limit isn&apos;t set.
<p>
This implementation is very efficient since it does not create any additional
table-like data structures. The FIFO ordering information is
maintained by attaching ordering metadata to cache entries.</p>
