Worked on the block/elasticgraph repository to deliver a configurable JSON schema strictness feature for the core indexing pipeline. This enhancement introduced two new settings that allow teams to control how strictly incoming events are validated against the schema, balancing data completeness with schema compliance. By enabling or disabling the acceptance of omitted or extra fields, the solution reduces the risk of data loss as event schemas evolve while maintaining backward compatibility. The work involved API development, schema design, and thorough testing, all implemented in Ruby, resulting in a more resilient and flexible indexing process for diverse data ingestion scenarios.
