问题 I'm trying to test the Spark-HBase connector in the GCP context and tried to follow the instructions, which asks to locally package the connector, and I get the following error when submitting the job on Dataproc (after having completed these steps). Command (base) gcloud dataproc jobs submit spark --cluster $SPARK_CLUSTER --class com.example.bigtable.spark.shc.BigtableSource --jars target/scala-2.11/cloud-bigtable-dataproc-spark-shc-assembly-0.1.jar --region us-east1 -- $BIGTABLE_TABLE Error

问题 I am new to Google Cloud Bigtable and have a very basic question as to whether the cloud offering protects my data against user error or application corruption? I see a lot of mention on the Google website that the data is safe and protected but not clear if the scenario above is covered because I did not see references to how I can go about restoring data from a previous point-in-time copy. I am sure someone on this forum knows! 回答1: Updated 7/24/2020 : Bigtable now supports both backups and

问题 I am looking to finalize on Big table vs Big Query for my usecase of timeseries data. I had gone through https://cloud.google.com/bigtable/docs/schema-design-time-series This is for storing an Omniture data which contains information like website visitor key(some Long key), his cookie id(some Long key), timestamp series data web hits for his IP, cookie What can be used as the rowkey for Big table? I cannot be using timestamp or CookieId as a prefix, as I learn from the best practices. But

问题 We have a use case in the Streaming mode where we want to keep track of a counter on BigTable from the pipeline (something #items finished processing) for which we need the increment operation. From looking at https://cloud.google.com/bigtable/docs/dataflow-hbase, I see that append/increment operations of the HBase API are not supported by this client. The reason stated is the retry logic on batch mode but if Dataflow guarantees exactly-once, why would supporting it be a bad idea since I know
