--------------------------------
Summary: DeadLock caused by blocked operation in IntoOperator
Key: IOTDB-4978
URL: https://issues.apache.org/jira/browse/IOTDB-4978
Project: Apache IoTDB
Issue Type: Bug
Components: Core/Query
Reporter: Yuan Tian
Assignee: Minghui Liu
There are only fixed threads for query execution, so we shouldn't let blocked
operation like rpc call in it. The following case may cause deadlock:
2c machines
2 clients concurrently execute `select into`, then IntoOperator will occupy the
only two query execution threads to send write requests which are blocked
operation. However, write operation will fetch schema which will only need
query execution threads to do that. Bump, deadlock borns.
