Background iceberg split loader

[liupan664021]

Hello, is there any plan to put the icebeg split source in bakground? or is anyone working on this?

@Override
    public CompletableFuture<ConnectorSplitBatch> getNextBatch(ConnectorPartitionHandle partitionHandle, int maxSize)
    {
        // TODO: move this to a background thread
        List<ConnectorSplit> splits = new ArrayList<>();
        Iterator<FileScanTask> iterator = limit(fileScanIterator, maxSize);
        while (iterator.hasNext()) {
            FileScanTask task = iterator.next();
            if (!task.deletes().isEmpty()) {
                throw new TrinoException(NOT_SUPPORTED, "Iceberg tables with delete files are not supported: " + schemaTableName);
            }
            splits.add(toIcebergSplit(task));
        }
        return completedFuture(new ConnectorSplitBatch(splits, isFinished()));
    }
