Performance Ranking (fastest to slowest):

Format	Notes
Native	Most efficient. Column-oriented, minimal parsing. Recommended.
RowBinary	Efficient row-based alternative
JSONEachRow	Easier to use but expensive to parse

Example:

python

# Use Native format for best performance
client.execute("INSERT INTO events VALUES", data, settings={'input_format': 'Native'})
