AM
Head of Data Science center of excellence at Ameriabank CJSC
Highly efficient data processing, optimizes infrastructure, and offers good integrations
DuckDB is very fast. If we don't have enough memory, we can use swap. For instance, if we use a fast storage space, the system volume in Kubernetes could be a fast swap for DuckDB if we have memory limits. In our framework, DuckDB is five times faster than Spark in some cases. It has an extensive SQL dialect, many SQL Windows functions, and good integration with Polars. We can easily use SQL and Pandas framework in Python to process data.

"I don't think the solution is very scalable, because the scalability of the performance when using more than one process is not very good."
"The solution could improve by providing partitioning and encryption."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"In the next release, it should support JSON, XML, and replication with third-party tools."
