---------------------------------
Summary: Move limit&slimit parser to Server side
Key: IOTDB-334
URL: https://issues.apache.org/jira/browse/IOTDB-334
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Jialin Qiao
In our query process, SQL will be analyzed by Antlr in the server-side, then
generated to a logical plan.
However, query SQL is also parsed in the client (IoTDBQueryResultSet) by the
following statement to get the value of slimit and limit.
String[] splited = sql.toUpperCase().split("\\s+");
This causes extra parsing for a query, which will slow down the query speed.
I recommend moving the limit&slimit parsing to the server-side.
