How can I batch queries using asyncpg?

You can batch queries in asyncpg by using the executemany method, which allows you to execute multiple queries in one call.

Can you show me an example of using executemany?

Sure! Here's a simple example:

import asyncpg

async def batch_insert(conn, data):
    await conn.executemany('INSERT INTO my_table (column1, column2) VALUES ($1, $2)', data)

This will insert multiple rows into my_table.

What kind of data structure should I use for the data parameter?

The data parameter should be a list of tuples, where each tuple contains the values for each row you want to insert. For example:

data = [(1, 'value1'), (2, 'value2'), (3, 'value3')]
