public boolean enable_user_defined_functions

enable_scripted_user_defined_functions

public boolean enable_scripted_user_defined_functions

enable_user_defined_functions_threads

public boolean enable_user_defined_functions_threads

Optionally disable asynchronous UDF execution. Disabling asynchronous UDF execution also implicitly disables the security-manager! By default, async UDF execution is enabled to be able to detect UDFs that run too long / forever and be able to fail fast - i.e. stop the Cassandra daemon, which is currently the only appropriate approach to "tell" a user that there's something really wrong with the UDF. When you disable async UDF execution, users MUST pay attention to read-timeouts since these may indicate UDFs that run too long or forever - and this can destabilize the cluster.

user_defined_function_warn_timeout

public long user_defined_function_warn_timeout

Time in milliseconds after a warning will be emitted to the log and to the client that a UDF runs too long. (Only valid, if enable_user_defined_functions_threads==true)

user_defined_function_fail_timeout

public long user_defined_function_fail_timeout

Time in milliseconds after a fatal UDF run-time situation is detected and action according to user_function_timeout_policy will take place. (Only valid, if enable_user_defined_functions_threads==true)

user_function_timeout_policy

public Config.UserFunctionTimeoutPolicy user_function_timeout_policy

Defines what to do when a UDF ran longer than user_defined_function_fail_timeout. Possible options are: - 'die' - i.e. it is able to emit a warning to the client before the Cassandra Daemon will shut down. - 'die_immediate' - shut down C* daemon immediately (effectively prevent the chance that the client will receive a warning). - 'ignore' - just log - the most dangerous option. (Only valid, if enable_user_defined_functions_threads==true)
