Method Detail

plan

TableOperations.ImportOptions plan(LoadPlan service)

Load files in the directory to the row ranges specified in the plan. The plan should contain at least one entry for every file in the directory. When this option is specified, the files are never examined so it is possible to send files to the wrong tablet.

executor

TableOperations.ImportOptions executor(Executor service)

Files are examined to determine where to load them. This examination is done in the current process using multiple threads. If this method is not called, then the client property bulk.threads is used to create a thread pool. This property defaults to "8C".

Parameters:

service - Use this executor to run file examination task

threads

TableOperations.ImportOptions threads(int numThreads)

Files are examined to determine where to load them. This examination is done in the current process using multiple threads. If this method is not called, then the client property bulk.threads is used to create a thread pool. This property defaults to "8C".

Parameters:

numThreads - Create a thread pool with this many thread to run file examination task.
