Liquibase–JDBC driver: graceful cancellation and timeout handling for changeSets
Goal and constraints Defining the expected behavior when a changeSet is cancelled or exceeds a time limit is the primary goal. Liquibase currently lacks a native cancellation API; JDBC‑level socket or login timeouts can abort the statement but may leave the database in a partially applied state if the changeSet is not transactional. The runInTransaction flag
liquibaseNetBeans JDBC Connection Pool Configuration Lacks Configurable Wait Timeout
Goal: Prevent the NetBeans IDE UI from blocking indefinitely when a JDBC connection pool is exhausted during concurrent database operations. Constraint: The connection pool editor in the Services window exposes initial size, maximum size, and statement cache, but does not provide a configurable wait‑timeout or acquisition timeout for obtaining a connection w
netbeansConfiguring JDBC Savepoint usage for safe rollback after DDL schema changes
Goal Ensure that a transaction can be rolled back to a known point after executing a schema‑altering statement (e.g., ALTER TABLE) so that any unintended data changes are undone while preserving the ability to commit other work. Constraints / Uncertainty Many relational databases issue an implicit commit when a DDL statement is executed, which may terminate
javaRegional timestamp stored with unexpected offset in Liquibase TIMESTAMP column
Liquibase delegates timestamp binding to the JDBC driver, so a zone-offset date-time inserted into a TIMESTAMP or TIMESTAMPTZ column can be stored with an unexpected offset. The stored instant may depend on the driver, column type, JVM default time zone, and database session time zone. Offline changelog validation does not detect this runtime shift. Goal: de
