The MongoDB Sharding Team has established a new division in Barcelona, led by Kal Manassiev, who joined the company from Microsoft SQL Server and AWS. The team builds frameworks and tools that abstract away difficult distributed systems problems for database users, freeing developers to focus on working with data itself. Recently completed projects include Distributed Transactions and Retryable Writes, and upcoming efforts aim to make sharding even more transparent to developers. The team is growing, with plans to hire more engineers to tackle technical challenges such as workload balancing and consistency. Kal Manassiev has a strong background in distributed systems and has been instrumental in building the Barcelona-based Sharding team, which is known for its collaborative culture and opportunities for career growth.
