Method Detail

useOldPlanner

public EnvironmentSettings.Builder useOldPlanner()

Sets the old Flink planner as the required module.

This is the default behavior.

useBlinkPlanner

public EnvironmentSettings.Builder useBlinkPlanner()

Sets the Blink planner as the required module. By default, useOldPlanner() is enabled.

useAnyPlanner

public EnvironmentSettings.Builder useAnyPlanner()

Does not set a planner requirement explicitly.

A planner will be discovered automatically, if there is only one planner available.

By default, useOldPlanner() is enabled.

inBatchMode

public EnvironmentSettings.Builder inBatchMode()

Sets that the components should work in a batch mode. Streaming mode by default.

inStreamingMode

public EnvironmentSettings.Builder inStreamingMode()

Sets that the components should work in a streaming mode. Enabled by default.

withBuiltInCatalogName

public EnvironmentSettings.Builder withBuiltInCatalogName(String builtInCatalogName)

Specifies the name of the initial catalog to be created when instantiating a TableEnvironment. This catalog will be used to store all non-serializable objects such as tables and functions registered via e.g. TableEnvironment.registerTableSink(String, TableSink) or TableEnvironment.registerFunction(String, ScalarFunction). It will also be the initial value for the current catalog which can be altered via TableEnvironment.useCatalog(String).

Default: "default_catalog".

withBuiltInDatabaseName

public EnvironmentSettings.Builder withBuiltInDatabaseName(String builtInDatabaseName)

Specifies the name of the default database in the initial catalog to be created when instantiating a TableEnvironment. The database will be used to store all non-serializable objects such as tables and functions registered via e.g. TableEnvironment.registerTableSink(String, TableSink) or TableEnvironment.registerFunction(String, ScalarFunction). It will also be the initial value for the current database which can be altered via TableEnvironment.useDatabase(String).

Default: "default_database".

build

public EnvironmentSettings build()
