The text discusses a comparison between two data movement tools, PeerDB and Airbyte, specifically focusing on their performance in transferring large tables from Postgres to Snowflake. Both tools are open-source and available as Docker Compose applications. The benchmark test involved generating a 1.5TB table with 6 billion rows in Postgres and then transferring it to Snowflake using both PeerDB and Airbyte. Airbyte, which does not support parallelism, took 83 hours for the transfer. On the other hand, PeerDB implemented parallelism by logically partitioning the large table and streaming those partitions to Snowflake in parallel. With 32 threads, PeerDB completed the same task in under 5 hours, making it 16 times faster than Airbyte. Even with a single-threaded run, PeerDB was still approximately twice as fast as Airbyte. PeerDB's speed is attributed to its adoption of parallelism, configurable batching while reading from Postgres and writing to Snowflake, and the use of Avro for data transfer in binary format. The text also mentions that PeerDB is working on additional features to further improve performance. While Airbyte offers a wide variety of connectors, PeerDB focuses primarily on providing high-quality source and destination connectors for Postgres.
