### Bug Type (问题类型) performance (性能下降) ### Before submit - [x] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - Server Version: 1.5.0 (Apache Release Version) - Backend: Mysql - OS: CentOS 7.x ### Expected & Actual behavior (期望与实际表现) - 问题描述： 1、内存dump中mysql驱动实例呈线性增长趋势 2、gc回收后占用空间没有下降，直至内存溢出 - 问题分析 在ResultSetWrapper中创建和close方法中分别加入日志，发现存在一定比例的ResultSetWrapper没有正常调用关闭方法。 - 问题解决 在ResultSetWrapper中加入finalize方法，在回收前判断resultSet和statement有没有正常关闭，未关闭则处理 加入此处理后问题解决。 @Override protected void finalize() { try { if (this.resultSet != null && !this.resultSet.isClosed()) { LOG.warn("resultSet was not closed properly, forcing close via finalize"); this.resultSet.close(); } } catch (SQLException e) { throw new BackendException("Failed to close ResultSet", e); } finally { try { if (this.statement != null && !this.statement.isClosed()) { LOG.warn("statement was not closed properly, forcing close via finalize"); this.statement.close(); } } catch (SQLException e) { throw new BackendException("Failed to close Statement", e); } } } ### Vertex/Edge example (问题点 / 边数据举例) ```javascript ``` ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) ```javascript ``` -- This is an automated message from the Apache Git Service.
