In conclusion, ConnectorX uses **3x** less memory and **3x** less time compared with Pandas.

### Development Setup

To load the database seed data into the database, you will need `sqlplus`.

Install it from Oracle's website's InstantClient page: https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html.

On Linux, this can be done by:

```bash
wget https://download.oracle.com/otn_software/linux/instantclient/2370000/instantclient-sqlplus-linux.x64-23.7.0.25.01.zip
unzip instantclient-sqlplus-linux.x64-23.7.0.25.01.zip
mkdir /opt/oracle/instantclient_23_7/
mv instantclient_23_7/*.so /opt/oracle/instantclient_23_7/
mv instantclient_23_7/* /usr/bin/
export LD_LIBRARY_PATH=/opt/oracle/instantclient_23_7:$LD_LIBRARY_PATH
sqlplus -h
```

Run the Oracle tests with:
```bash
cat scripts/oracle.sql | sqlplus $ORACLE_URL_SCRIPT

cargo test --features all --test test_oracle -- --ignored
```
