Announcement
BigQuery can re-execute instructions (queries) to try to proactively detect performance, correctness, or functional regressions.
These re-executions will have no side effects and will happen with no additional cost or resource consumption.
Data access logs may show bigquery-adminbot@system.gserviceaccount.com when BigQuery re-executes an instruction.
Feature
Python UDFs are now
Generally Available
(GA).
You can use Python UDFs to implement a scalar function in Python and use it in a
SQL query. Python UDFs let you install third-party libraries from the
Python Package Index (PyPI) and let you access external
services using a Cloud resource connection.
Feature
You can now use the
AI.AGG function
to semantically aggregate unstructured input data based on natural language
instructions. This feature is in
Preview.
