Join Arm Treasure Data to discover how as part of their customer data platform, Arm Treasure Data utilizes Presto as the query engine processing over 1 million queries per day to support the data business of 500+ companies in three regions; US, EU, and Asia. Arm Treasure Data had been using Presto 0.205 and in 2019 started a big migration project to Presto 317. Although we performed extensive query simulations to check any incompatibilities, we faced many unexpected challenges during the migration at production that will be discussed.

Discussion Points:

  • Details on challenges and our key learnings
  • Latest updates on AWS Graviton2, the next generation of 64-bit Arm instance types that can be used for running Presto
