The Datastore connector for Hadoop is a Java library that enables Hadoop to process to read and write data to/from Cloud Datastore programmatically.
You are charged for per-operation costs for entities that are read or written to Datastore, according to Datastore pricing. Datastore costs more on average per byte than Google Cloud Storage, but allows more sophisticated and fine-graned access patterns to the data.
Getting the connector
Download the Datastore connector javadoc reference.
Using the connector
To configure and enable Datastore access, modify bigquery_env.sh and load it with bdutil:
./bdutil --bucket foo-bucket -n 5 -P my-cluster --env_var_files datastore_env.sh deploy
