+Version 2.0.9.1 endows AINode with covariate classification inference
capability, supports schema-level and table-level storage space statistics. It
adds set operations, CTE and multiple built-in functions for data query,
enables SQL debugging via DEBUG statements, and supports configuring auto-start
on boot. This version also contains legacy version improvements, bug fixes, and
comprehensive enhancements to database monitoring, performance and stability.
Details are as follows:
+
