Blockchain analysis platform Dune released a timetable for the decommissioning of SparkSQL and PostgreSQL on Twitter. They will be removed from the data explorer on May 15, editing will be disabled on June 15, and services will be discontinued on July 15. Dune reminded users that they need to use the DuneSQL migration tool to migrate to DuneSQL before July 15. Queries running on SparkSQL or PostgreSQL will no longer be updated in the future, but data in them can still be accessed.

Additionally, data ingestion for Polygon, BNB, Optimism, and Gnosis on their respective Postgres instances was stopped on April 20. Meanwhile, in the short term, Spells will continue to run on SparkSQL but be queryable by DuneSQL. The Dune team is already testing a new version of Spellbook that will run entirely on DuneSQL, closing the last remaining compatibility gap.
