If you want to use a custom policy, ensure the policy has the following permissions:Ĭurl -L Set up an ALB to access Grafana server externallyĪs a best practice, we’ll create an ALB that uses a Target Group to forward HTTP requests to the EC2 instance on port 3000 (which is the default Grafana port). Next, create an Amazon Linux 2 Amazon Machine Image (AMI) based EC2 instance and assign an IAM role that has the managed policy arn:aws:iam::aws:policy/AmazonPrometheusQueryAccess attached to it. To begin, log in to the EC2 console on your AWS account. Query the metrics from AMP to verify the setup works as expected.Add AMP as data source in Grafana using SigV4 authentication.Set up an Application Load Balancer (ALB) to access Grafana server externally.Enable SigV4 authentication through built-in AWS SDK in Grafana (v7.3.5 onward).

In this article, we will look at how to configure a self-hosted open source Grafana server on Amazon Elastic Compute Cloud (Amazon EC2) to connect an AMP data source and create a dashboard. We can query the metrics from the AMP environment using Amazon Managed Grafana, a self-hosted Grafana server, or using the HTTP APIs.

However, I have not found any way to query older copy of data using Athena like in Spark.

As per the docs you provided, automatic manifest update can be disabled byĪLTER TABLE delta. However, the only way I have found is by not updating the manifest file i.e., if the manifest file is not updated Athena will refer to old version of data. I understand that you were not able to query the previous version in delta lake using Athena.Īfter taking the case offline, I have reviewed the delta lake docs, Athena docs internal and external but was not able to find any information hinting the ability to query previous version of data using Athena. Thank you for contacting AWS Premium Support. Thanks in, thanks for tagging the issue! Here's the response from the AWS support team ( Just in case it helps somebody else in a similar situation) : Obs.: The manyfest file creation step and the CREATE EXTERNAL TABLE from athena step described in were also executed prior to the above SQL query attemptĪny clarification regarding the matter would be really appreciated! SELECT * FROM "delta_db"."delta_table" VERSION AS OF 2 īut running this syntax in athena results in the following error: We would like to run a very similar SQL query through Athena instead, in order to retrieve a specific version of a table, for example:

("delta").option("versionAsOf", 2).load(target_s3_path) Those were also successful and we were able to read its content and check the multiple versions of the delta table that were written.įrom pyspark code, we had no issues reading any of the table versions specifically, as follows: PreLastOperationDF = deltaTable.history(2) LastOperationDF = deltaTable.history(1) # get the last operation
