Jialin Qiao commented on IOTDB-482: ----------------------------------- For all query types with value filter, such as where s1=1 or s2=1, we will construct a TimeGenerator to get the timestamp in the result. In the above case, the generator tree is OrNode(LeafNode(s1=1), LeafNode(s2=1)). In the engine, each leafnode corresponds to a SeriesRawDataPointReader. It's possible to use SeriesRawDataBatchReader in each leafnode and internal nodes to speed up the time generator. It could also be optimized in the TsFile module. > Vectorized TimeGenerator > ------------------------ > > Key: IOTDB-482 > URL: https://issues.apache.org/jira/browse/IOTDB-482 > Project: Apache IoTDB > Issue Type: Sub-task > Components: Core/Engine > Reporter: atoildw > Assignee: atoildw > Priority: Major > Fix For: 0.10.0-SNAPSHOT > > -- This message was sent by Atlassian Jira (v8.3.4#803005)
