This repository is based on https://github.com/duckdb/extension-template, check it out if you want to build and ship your own DuckDB extension.
The OML extension let's you load OML files directly into DuckDB.
Use Power_Consumption_load(filename)
to load OML data from a given OML file into a predetermined table with the following schema:
CREATE TABLE IF NOT EXISTS Power_Consumption (
experiment_id VARCHAR,
node_id VARCHAR,
node_id_seq VARCHAR,
time_sec VARCHAR NOT NULL,
time_usec VARCHAR NOT NULL,
power REAL NOT NULL,
current REAL NOT NULL,
voltage REAL NOT NULL
);
Alternatively the function OmlGen(filename)
can be used to dynamically create a table with a schema determined by the metadata of the OML file. The data of the OML file will then be loaded into the new table.
The extension is automatically loaded into DuckDB after this project is built. This means that DuckDB should simply be run as normal, that is:
./build/<release|debug>/duckdb
When DuckDB is running, use the commands of the previous section.
The extension can be build by running the command:
make
In order to enable debugging, the following command should be run instead:
make debug
