------------------------------------------
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.
