[jira] [Created] (IOTDB-1186) Remove redundant sync meta leader in query process for cluster module
Xinyu Tan created IOTDB-1186: Summary: Remove redundant sync meta leader in query process for cluster module Key: IOTDB-1186 URL: https://issues.apache.org/jira/browse/IOTDB-1186 Project: Apache IoTDB Issue Type: Improvement Components: Core/Cluster Reporter: Xinyu Tan Currently, the coordinator will create one remoteSeriesReader for each timeseries if the timeseries belongs to other nodes, and the coordinator will try to perform a sync meta leader in each remoteSeriesReader's initManagedSeriesReader function, which cost a lot of network overhead. Actually, we can just sync meta leader once for one query. -- This message was sent by Atlassian Jira (v8.3.4#803005)
[jira] [Created] (IOTDB-1173) auto-create schema improvement for createMultiTimeSeriesPaln
Xinyu Tan created IOTDB-1173: Summary: auto-create schema improvement for createMultiTimeSeriesPaln Key: IOTDB-1173 URL: https://issues.apache.org/jira/browse/IOTDB-1173 Project: Apache IoTDB Issue Type: Improvement Reporter: Xinyu Tan Fix For: master branch currently,cluster will auto-create storage groups for createMultiTimeSeriesPaln if related storage groups hasn't been created. However, if one createMultiTimeSeriesPaln have 10 paths which belong to same storage group, current auto-create schema logic will perform 10 setStroageGroup opeartions in meta Group,which cause a big waste of time for this request. -- This message was sent by Atlassian Jira (v8.3.4#803005)

[jira] [Created] (IOTDB-1121) Session example executeNonQueryStatement parse bug
Xinyu Tan created IOTDB-1121: Summary: Session example executeNonQueryStatement parse bug Key: IOTDB-1121 URL: https://issues.apache.org/jira/browse/IOTDB-1121 Project: Apache IoTDB Issue Type: Bug Components: Client/Java Reporter: Xinyu Tan Attachments: image-2021-01-25-10-44-05-989.png currently, sessionExample contains a executeNonQueryStatement method which will cause server to report a bug command like this: !image-2021-01-25-10-44-05-989.png|thumbnail! this is because our currently the server logic of executeNonQueryStatement can execute multiple statement just like "insert into root.sg1.d1(timestamp,s1) values(200, 1);insert into root.sg1.d1(timestamp,s1) values(300, 1)", even it can not figure `insert into root.sg1.d1(timestamp,s1) values(200, 1);`.So I would like to delete this ';' before is can support multiple statement -- This message was sent by Atlassian Jira (v8.3.4#803005)
[jira] [Created] (IOTDB-1099) Optimize insertablets logic in cluster module
Xinyu Tan created IOTDB-1099: Summary: Optimize insertablets logic in cluster module Key: IOTDB-1099 URL: https://issues.apache.org/jira/browse/IOTDB-1099 Project: Apache IoTDB Issue Type: Improvement Components: Core/Cluster Reporter: Xinyu Tan Currently, cluster module will process insertablets rpc by spliting it to multiple insertablet statements one by one, and each of them will take up a raft log, which need to complete the RaftLogManager's lock and be replicated to followers in one raft log. In some user cases, a inserttablets will have 160 tablets, so this single client insertablets rpc will take up 160 raft log containing insertabletPlan to replicate, which maybe optimized to one raft log containing insertablets if these devices all belong to same data group; Therefore, we can process insertablets by grouping them to several insertablets according to these belonged data groups, just like the createMultiTimeSeriesPlan in current implementation. -- This message was sent by Atlassian Jira (v8.3.4#803005)
