little-emotion opened a new pull request #294: [IOTDB-152]return data type in TSExecuteStatementResp URL: https://github.com/apache/incubator-iotdb/pull/294 When executing the query statement, after sending executeStatement request to server and return the execResp, the client send several TSFetchMetadata requests to server for fetching data types of the query columns. So we can return dataTypes in executeStatement request to avoid the following fetchmetaData requests. Thank Rui Lei for discovering this problem.
