             Summary: PageMemoryPartitionStorage#write() can leak page slots
                 Key: IGNITE-16980
                 URL: https://issues.apache.org/jira/browse/IGNITE-16980
             Project: Ignite
          Issue Type: Bug
          Components: persistence
            Reporter: Roman Puchkovskiy
            Assignee: Kirill Tkalenko
             Fix For: 3.0.0-alpha5


{{public void write(DataRow row) throws StorageException {}}
{{    try {}}
{{        TableDataRow dataRow = wrap(row);}}

{{        freeList.insertDataRow(dataRow);}}

{{        tree.put(dataRow);}}
{{    } catch (IgniteInternalCheckedException e) {}}
{{        throw new StorageException("Error writing row", e);}}
{{    }}}
{{}}}

This code always occupies a slot in a data page, even if the key was already put to the partition. So, if 2 puts with same key occur, one page slot is wasted.
