Using Python to Operate Apache Ignite

To operate the Apache Ignite database using Python, you need to first install the 'pyignite' library. You can use the 'pip' command for installation: pip install pyignite The following is a complete Python code example that demonstrates how to connect to an Apache Ignite database and perform insert, query, update, and delete operations: python from pyignite import Client #Connect to the Apache Ignite database client = Client() client.connect('127.0.0.1', 10800) #Create a cache cache_config = { 'name': 'my_cache', 'atomicity_mode': 'transactional', 'backups': 1 } client.create_cache(cache_config) #Insert Data with client.tx_start(): cache = client.get_cache('my_cache') cache.put(1, 'John') cache.put(2, 'Alice') cache.put(3, 'Bob') #Query data with client.tx_start(): cache = client.get_cache('my_cache') result = cache.get(1) Print (result) # Output: 'John' #Update data with client.tx_start(): cache = client.get_cache('my_cache') cache.put(1, 'Jonathan') #Delete data with client.tx_start(): cache = client.get_cache('my_cache') cache.remove_key(2) #Disconnect from database client.close() In the above example, we first connect to the Apache Ignite database through the 'Client()' class. Then use the 'connect()' method to specify the host and port number to connect to the database. Next, we will use 'create'_ The cache() method creates a file named 'my'_ The cache of 'cache'. This method takes a dictionary containing cache configuration as a parameter and can set different configuration options as needed. Then, we used the 'put ()' method to insert some data into the cache, and used the 'get ()' method to query a piece of data. In transactions, we can use the 'put()' method to update data and use the 'remove' method_ The key() ` method is used to delete data. Finally, we use the 'close()' method to close the connection to the database. Please modify the parameters such as host name, port number, and cache name according to the actual situation.
