[GitHub] [iotdb] noorall opened a new issue #4385: Query dataset momory leak on server caused by python client
noorall opened a new issue #4385:
URL: https://github.com/apache/iotdb/issues/4385
version: 0.12.2 & 0.13.0-SNAPSHOT
def close_operation_handle(self) is not worked as expected.
I'm testing the performance of java client and python client. During the test, I found that Python client will lead to memory leakage of sever, which leads to continuous query performance degradation when using Python client for continuous query operations.
My python client test code is：
```
for i in range(0, times):
session_dataset = session.execute_query_statement(sql)
while session_dataset.has_next():
session_dataset.next()
session_dataset.close_operation_handle()
```
My java client test code is：
```
for (int i = 0; i < times; i++) {
SessionDataSet sessionDataSet = session.executeQueryStatement(sql);
while (sessionDataSet.hasNext()) {
sessionDataSet.next();
}
sessionDataSet.closeOperationHandle();
}
```
After continuous query operation with Python client, the memory usage of the server is:
```
2021-11-15 12:26:15,177 [Thread-0] INFO o.a.i.d.s.IoTDBShutdownHook:33 - IoTDB exits. Jvm memory usage: 1 GB 23 MB 111 KB 888 B
```
After continuous query operation with Java client, the memory usage of the server is:
```
2021-11-15 08:38:42,582 [Thread-0] INFO o.a.i.d.s.IoTDBShutdownHook:33 - IoTDB exits. Jvm memory usage: 0 GB 303 MB 846 KB 952 B
```
