---------------------------------
Summary: Parallel Raw data query
Key: IOTDB-389
URL: https://issues.apache.org/jira/browse/IOTDB-389
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Jialin Qiao
Currently, IoTDB executes a query in a single thread, which could be
accelerated by multi-thread.
We could apply the producer-consumer module and the changes could be made in
the NewEngineDataSetWithoutValueFilter.
A potential solution: Add a queue that buffers a predefined number of
BatchDatas for each time series. Once a BatchData is consumed, a thread put a
new BatchData of this time series into the queue. The degree of parallelism
could be configured or adjusted dynamically.
