  setLoggingLevel

  public static boolean setLoggingLevel(String logLevel)

  Dynamically set the log level for the ‘com.gpudb’ logger at runtime. Supports multiple SLF4J backend implementations:

  • Logback - Native SLF4J implementation (most common)
  • Log4j2 - Apache Log4j 2.x via slf4j-log4j2 binding
  • JUL - Java Util Logging via slf4j-jdk14 binding

  Note: slf4j-simple does not support runtime log level changes. For slf4j-simple, set the level via system property at startup: -Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG

  Parameters:

  logLevel - One of the supported log levels: TRACE, DEBUG, INFO, WARN, ERROR, OFF. null value is treated as ‘OFF’.

  Returns:

  true if the log level was successfully set, false if no supported backend was detected or an error occurred.

• ​

  setDependencyLogLevel

  public static boolean setDependencyLogLevel(String loggerName, String logLevel)

  Sets the log level for a dependent library logger. Useful for silencing verbose third-party libraries.

  Parameters:

  loggerName - The fully qualified logger name (e.g., “org.apache.http”)

  logLevel - The desired log level

  Returns:

  true if successful, false otherwise
