### [Data-Driven, Interoperable Core Banking: A BIAN and MongoDB Perspective](https://yomu.fyi/post/data-driven-interoperable-core-banking-a-bian-and-mongodb-perspective.md)

Core banking modernization is hindered by semantic fragmentation, where the same banking concepts are defined differently across systems, creating duplicated logic and fragile integrations. The Banking Industry Architecture Network (BIAN) provides a shared semantic foundation by defining common banking domains, boundaries, and service interactions, enabling a composable architecture. MongoDB’s document model, using JSON as both storage and interchange format, allows banks to represent business domains flexibly and evolve incrementally without schema migrations, eliminating the ORM impedance mismatch. MongoDB ensures financial integrity through single-document atomicity for common ledger updates and multi-document ACID transactions for complex cross-domain workflows, while Change Streams enable event-driven operations. Together, BIAN and MongoDB create an operating model for continuous transformation, where teams modernize domain by domain, supported by a shared business language and a scalable, flexible data platform.


### [ClickHouse release 26.9](https://yomu.fyi/post/clickhouse-release-26-9.md)
- Company: [Clickhouse](https://yomu.fyi/company/clickhouse.md)
- Published: Sep 23, 2026
- Type: Announcement

ClickHouse 26.9 ships with 56 new features, 135 performance optimizations, and 464 bug fixes. Among the highlights are conditional LIMIT boundaries that control output based on ordered stream values, incremental refreshes for append-only materialized views, and disk spilling for high-cardinality DISTINCT queries that automatically spills when memory usage reaches half the limit. The CREATE TOKEN feature issues time-limited credentials with a default lifetime of 30 minutes and restricted privileges, reducing the impact of leaked keys. Arithmetic operations between DateTime and Time types now support configurable overflow behaviors—throw, saturate, or ignore. PromQL support expands in a private preview on ClickHouse Cloud, bracket syntax simplifies JSON subcolumn access, and queries for min, max, and count receive performance improvements.
