Method Detail

load

public static ExistingSavepoint load(org.apache.flink.api.java.ExecutionEnvironment env,

                              throws IOException

Deprecated.

Loads an existing savepoint. Useful if you want to query, modify, or extend the state of an existing application. The savepoint will be read using the state backend defined via the clusters configuration.

Parameters:

env - The execution environment used to transform the savepoint.

path - The path to an existing savepoint on disk.

Throws:

IOException
