### 3. create tpc-h tables. modify `conf/doris-cluster.conf` to specify doris info, then run script below.

    ./bin/create-tpch-tables.sh

### 4. load tpc-h data. use -h for help.

    NOTICE: At present, Doris's query optimizer and statistical information functions are not complete, so we rewrite some queries in TPC-H to adapt to Doris' execution framework, but it does not affect the correctness of the results. The rewritten SQL is marked with "Modified" in the corresponding .sql file.

    A new query optimizer will be released in subsequent releases.
