Pymongo and SSL/TLS Connection to MongoDB

PyMongo SSL/TLS configuration requires setting tls=True and optionally tlsCAFile for server certificate validation. Mutual TLS needs tlsCertificateKeyFile and tlsCertificateKeyFilePassword for client authentication. Deprecated ssl parameters are replaced by tls-prefixed options for improved security and consistency.

Handling MongoDB Transactions with Pymongo

Pymongo, Python modulesMongoDB, Pymongo, Transactions

MongoDB transactions often face pitfalls like exceeding the transaction lifetime, which defaults to 60 seconds. Common errors include LockTimeout, TransientTransactionError, and WriteConflict. Efficient transaction handling requires short operations, robust retry logic, and awareness of causal consistency. Ensure your deployment supports transactions and manage errors effectively.

Customizing Serialization and Deserialization in MongoDB with Pymongo

Pymongo, Python modulesDeserialization, MongoDB, Pymongo, Serialization

Serialization and deserialization logic plays a crucial role in application performance. BSON offers efficiency over JSON, especially for binary data, but poorly executed methods can lead to bottlenecks. Implementing batch operations and error handling enhances performance, while versioning ensures compatibility across data structures.
