BulkInserter.WorkerList()
Creates an empty
BulkInserter.WorkerList that can be populated manually
with worker URLs to support multi-head ingest. |

Creates a
BulkInserter.WorkerList and automatically populates it with the
worker URLs from GPUdb to support multi-head ingest. |

BulkInserter.WorkerList and automatically populates it with the
worker URLs from GPUdb to support multi-head ingest. |

BulkInserter.WorkerList that can be populated manually
with worker URLs to support multi-head ingest. Note that worker URLs
must be added in rank order, starting with rank 1, and all worker
ranks must be included; otherwise insertion may fail for certain
data types.public BulkInserter.WorkerList(GPUdb gpudb) throws GPUdbException
BulkInserter.WorkerList and automatically populates it with the
worker URLs from GPUdb to support multi-head ingest. (If the
specified GPUdb instance has multi-head ingest disabled, the worker
list will be empty and multi-head ingest will not be used.) Note that
in some cases, workers may be configured to use more than one IP
address, not all of which may be accessible to the client; this
constructor uses the first IP returned by the server for each worker.
To override this behavior, use one of the alternate constructors that
accepts an IP regex
