## Usage

These scripts are used to make tpc-h test.
follow the steps below:

### 1. build tpc-h dbgen tool.

    ./bin/build-tpch-dbgen.sh

    If the build failed in dbgen tools' compilation, update your GCC version or change download link used by wget in build-tpch-dbgen.sh from ".../TPC-H_Tools_v3.0.0new.zip" to ".../TPC-H_Tools_v3.0.0.zip"

### 2. generate tpc-h data. use -h for more infomations.

    ./bin/gen-tpch-data.sh -s 1

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

    ./bin/create-tpch-tables.sh -s 1

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

    ./bin/load-tpch-data.sh

### 5. run tpc-h queries.

    ./bin/run-tpch-queries.sh -s 1

    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.

    Currently, differnt scales use the same suite of query sqls.
