To complete this guide, you will need permissions to create a read-only user on Presto.
To connect Monte Carlo to a Presto cluster to run data health SQL queries, follow these steps:
- Create a Presto cluster for Monte Carlo's data health queries using AWS EMR. Alternatively, you may use an existing cluster that you already have in your environment.
- Ensure that Monte Carlo's data collector has network connectivity to the cluster.
- Create a read-only service account on Presto if necessary.
- Provide service account credentials to Monte Carlo.
Monte Carlo supports basic authentication or custom certificates for Presto connections. Please create a read-only user for Monte Carlo, or obtain a certificate file that enables authentication to Presto.
You will provide connection details for Presto using Monte Carlo's CLI:
- Please follow this guide to install and configure the CLI.
- Please use the command
montecarlo integrations add-prestoto set up Presto connectivity. For reference, see help for this command below:
