-----------------------------
Resolution: Duplicate
> Vectorize the TimeGenerator
> ---------------------------
>
> Key: IOTDB-454
> URL: https://issues.apache.org/jira/browse/IOTDB-454
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: Jialin Qiao
> Priority: Minor
>
> 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.
