## A Multithreaded, Transaction-Based Locking Strategy for Containers Bob Steagall CppCon 2020 KEWB COMPUTING ## Overview • Sharing a container among multiple threads • A motivating problem • Some modification of an update group is treated as a single transaction, which either succeeds completely, or fails completely - Consistent: Each transaction can only bring the update group (and the enclosing enclosing container) from one valid state to another, maintaining all invariants - Isolated: Each transaction must ensure that concurrent execution of other transactions leaves its update group (and the container)

Toward Standard C++ Dependency Management ## BILL HOFFMAN & BRET BROWN ## 20 23 October 01 - 06 ## Libraries: A First Step Toward Standard C++ Dependency Management October 3, 2023 Bloomberg Engineering portable as the code they contain! ✓ Projects should be “cattle,” not “pets”! ## Why dependency management? Consensus: Managing dependencies == way too hard Q: Which of these do you find frustrating about following names: jsonlogConfig.cmake Jsonlog-config.cmake # ... CMake gives you some dependency management tips here ... Aside: Coloring and bolding added for emphasis ## Motivation: What would we design

# CS 591 K1: Data Stream Processing and Analytics Spring 2020 2/25: State Management Vasiliki (Vasia) Kalavri vkalavri@bu.edu ## State in dataflow computations Any non-trivial streaming computation 3cea6fb1/p4_2.jpg) What state types can you think of? • Count, sum, list, map, ... ## State management in Apache Flink All data maintained by a task and used to compute results: a local or instance state is stored, accessed, and maintained. State backends are responsible for: • local state management - checkpointing state to remote and persistent storage, e.g. a distributed filesystem or a database

• Run-time database configuration • Dynamically defining a database • Connection Management • Connection Pooling • Framework Integration • Executing Queries • Managing Bulk Inserts Transactions Context manager Decorator • Nesting Transactions • Explicit transaction • Autocommit Mode • Changes in 3.0 • Backwards-incompatible • New stuff • API so if the username is taken the database will raise an IntegrityError. try: with database.transaction(): # Attempt to create the user. If the username is taken, due to the unique constraint

"SpringTestContext" group anymore (for ease of using custom groups) Package org.springframework.transaction * added "validateExistingTransaction" property to AbstractPlatformTransactionManager, for throws TransactionSystemException in case of unexpected internal transaction state * JtaTransactionManager detects JBoss 4.2 transaction rollbacks caused by a timeout, throwing a meaningful exception * * fixed WebSphereUowTransactionManager to correctly detect an existing global transaction (ignoring local tx contexts) Package org.springframework.ui * fixed ModelMap's "mergeAttributes" to
