Migrating the candle_data table from PostgreSQL to QuestDB addresses performance limitations of row-based storage by leveraging QuestDB's columnar storage and vectorized execution, improving query latency and ingestion throughput. However, partial migration requires robust synchronization mechanisms like CDC or ETL pipelines to maintain data consistency across both databases.
Avoiding partial migrations without proper synchronization can lead to operational complexity and data inconsistency issues. Full migration is recommended if benchmarks show significant performance gains and resources are available for schema adjustments and team training.
