Yuan Tian created IOTDB-5525: -------------------------------- Summary: Can't find device's data partition after partition fetcher Key: IOTDB-5525 URL: https://issues.apache.org/jira/browse/IOTDB-5525 Project: Apache IoTDB Issue Type: Bug Components: Core/Engine Reporter: Yuan Tian Assignee: Yuan Tian
This issue records the following four things we meet in geely POC: 1. Previously, while calculating TTimeSlot for each SeriesSlot, we mistakenly replace previous one with current one which cause the TTimeSlot is incomplete for each SeriesSlot. In write case, we may get IndexOutOfBound error in the later phase. 2. Accelerate the distribution plan phase for {{{}group by level query{}}}, reducing time complexity from O(N^2) to O(N) for each data region 3. Correct the memory estimation for AggregationOperator. 4. Correct the default value for {{seriesPartitionExecutorClass}} from {{APHashExecutor}} to {{BKDRHashExecutor}} which is same as the one in config file. -- This message was sent by Atlassian Jira (v8.20.10#820010)
