Datasette handles this for you by maintaining a queue of writes to be executed against a given database. Plugins can submit write operations to this queue and they will be executed in the order in which they are received. \n                 This method can be used to queue up a non-SELECT SQL query to be executed against a single write connection to the database. \n                 You can pass additional SQL parameters as a tuple or dictionary. \n                 The method will block until the operation is completed, and the return value will be the return from calling  conn.execute(...)  using the underlying  sqlite3  Python library. \n                 If you pass  block=False  this behavior changes to \"fire and forget\" - queries will be added to the write queue and executed in a separate thread while your code can continue to do other things. The method will return a UUID representing the queued task. \n                 Each call to  execute_write()  will be executed inside a transaction.", "breadcrumbs": "[\"Internals for plugins\", \"Database class\"]", "references": "[]"}
