Dec 1, 2025December 2025 (broxus/tycho): Delivered stability and reliability improvements to the collator, introduced transactional AnchorsCache to support atomic rollback and commit of anchor state. Implemented performance and memory optimizations, including refactoring to faster point lookups and Box-wrapped ParsedMessage to improve ownership/borrowing semantics. Strengthened data persistence and disk management with a forced flush mechanism for immediate persistence and reduced RocksDB log size to control growth. These changes reduce risk of undefined behavior, improve runtime throughput, and lower long-term storage costs while sustaining data integrity.
