Over a two-month period, Kalantaevskii enhanced backend systems in C++ with a focus on database and compiler development. In the dragonflydb/dragonfly repository, he expanded the ZSET API to support the WITHSCORE option for ZRANK and ZREVRANK, updating core data structures and logic to return both rank and score in a single call, thereby improving client efficiency and aligning with Redis protocol expectations. Later, in ClickHouse/ClickHouse, he implemented dynamic target table support for CREATE MATERIALIZED VIEW by updating AST parsing to handle query parameters, increasing automation flexibility while maintaining backward compatibility and code clarity throughout both projects.
July 2025 monthly summary focusing on feature delivery in ClickHouse/ClickHouse. Implemented dynamic target table support in CREATE MATERIALIZED VIEW by enabling query parameters in the TO clause, with AST parsing/visitation updates to support parameterized targets. This change enables dynamic targeting of MV back-end tables, increasing flexibility for data pipelines and automation. The work was committed as 4334d1fb537e11a0274482fd9403614a555122b3 (message: "Support query parameters in TO section of MVs"). No major bugs fixed this month; stability and backward compatibility were preserved.
