/**
- * Callback at the beginning of checkpoint processing of a partition, for
example, when writing dirty pages or executing a fsync.
+ * Blocks physical destruction of partition.
+ *
+ * <p>When the intention to destroy partition appears, {@link
FilePageStore#isMarkedToDestroy()} {@code == true} and invoked
+ * {@link PersistentPageMemory#invalidate(int, int)} at the beginning. And
if there is a block, it waits for unblocking. Then it
+ * destroys the partition, {@link
FilePageStoreManager#getStore(GroupPartitionId)} will return {@code null}.</p>
+ *
+ * <p>It is recommended to use where physical destruction of the partition
may have an impact, for example when writing dirty pages and
+ * executing a fsync.</p>
+ *
+ * <p>To make sure that we can physically do something with the partition
during a block, we will need to use approximately the
+ * following code:</p>
+ * <pre><code>
+ * FilePageStore pageStore =
FilePageStoreManager#getStore(partitionId);
