Dask interface: Accept and forward the new if-exists query parameter

[amotl]

About

The new if-exists query parameter will be forwarded to Dask's to_sql() method. By default, influxio will use fail.

Details

When targeting the SQLAlchemy database interface, the target table will be created automatically, if it does not exist. The if-exists URL query parameter can be used to configure this behavior. The default value is fail.

• fail: Raise a ValueError.
• replace: Drop the table before inserting new values.
• append: Insert new values to the existing table.

Example usage

influxio copy \
    "http://example:token@localhost:8086/testdrive/demo" \
    "crate://crate@localhost:4200/testdrive?table=demo&if-exists=replace"
