Load Google Cloud Storage data into bigtable

问题

Is there an easy way or example to load Google Cloud Storage data into bigtable?

I have lots of json files generated by pyspark and i wish to load data into bigtable.

But I can not find an easy way to do that!

I have tried the python code from google-cloud-python and it work fined, but it just read data line by line into bigtable which was strange for me.

Any help would be greatly appreciated.

There is no simple tool to read data in Cloud Bigtable. Here are some options:

1. Import the files using Dataflow. This requires java development, and learning the Dataflow programming model.
2. Use Python (possibly with Pyspark) to read those json files, and write to Cloud Bigtable using a method called mutate_rows which write to Bigtable in bulk.

FYI, I work on the Cloud Bigtable team. I'm a Java developer, so I opt for #1. Our team has been working to improve our python experience. The extended team recently added some reliability improvements to make sure that mutate_rows is resilient for large jobs. We do not yet have any good examples of integrating with PySpark or Apache Beam's python SDK, but they are on our radar.
