--------------------------------
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.
