-------------------------
Summary: [ ClusterSchemaFetcher ] There is not enough memory to
execute current fragment instance
Key: IOTDB-4863
URL: https://issues.apache.org/jira/browse/IOTDB-4863
Project: Apache IoTDB
Issue Type: Bug
Components: mpp-cluster
Affects Versions: 0.14.0-SNAPSHOT
Reporter: 刘珍
Assignee: Yukun Zhou
m_1103_f857667
schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
data_region_consensus_protocol_class=org.apache.iotdb.consensus.multileader.MultiLeaderConsensus
1. 启动 3rep , 3C3D 集群
2. benchmark 创建元数据，写入数据
10sg ，10 schema region
5万设备，600 sensors/dev, 共3000万序列。
3.执行查询
select count(s_0) ,count(s_1),count(s_2),count(s_3) ,count(s_4)
,count(s_5),count(s_6),count(s_7),count(s_99) from root.** align by device
