Method Detail

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 is an in-memory catalog that will be used to store all temporary objects (e.g. from TableEnvironment.createTemporaryView(String, Table) or TableEnvironment.createTemporarySystemFunction(String, UserDefinedFunction)) that cannot be persisted because they have no serializable representation.

It will also be the initial value for the current catalog which can be altered via TableEnvironment.useCatalog(String).

Default: TableConfigOptions.TABLE_DATABASE_NAME.defaultValue().

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.

This database is an in-memory database that will be used to store all temporary objects (e.g. from TableEnvironment.createTemporaryView(String, Table) or TableEnvironment.createTemporarySystemFunction(String, UserDefinedFunction)) that cannot be persisted because they have no serializable representation.

It will also be the initial value for the current database which can be altered via TableEnvironment.useDatabase(String).

Default: TableConfigOptions.TABLE_DATABASE_NAME.defaultValue().

withConfiguration

public EnvironmentSettings.Builder withConfiguration(org.apache.flink.configuration.Configuration configuration)

Add extra configuration to EnvironmentSettings.

withClassLoader

public EnvironmentSettings.Builder withClassLoader(ClassLoader classLoader)

Specifies the classloader to use in the planner for operations related to code generation, UDF loading, operations requiring reflections on user classes, discovery of factories.

By default, this is configured using Thread.currentThread().getContextClassLoader().

Modify the ClassLoader only if you know what you're doing.

withCatalogStore

public EnvironmentSettings.Builder withCatalogStore(org.apache.flink.table.catalog.CatalogStore catalogStore)

withSqlFactory

public EnvironmentSettings.Builder withSqlFactory(org.apache.flink.table.expressions.SqlFactory sqlFactory)

Provides a way to customize the process of serializing Table API to a SQL string. This is useful, for example, for customizing the serialization of inline functions.

build

public EnvironmentSettings build()

Returns an immutable instance of EnvironmentSettings.
