It's recommended that you authenticate via the .Renviron file using DATABRICKS_HOST and DATABRICKS_TOKEN environment variables. You can also use Databricks CLI Configuration Profiles and DATABRICKS_CONFIG_FILE or DATABRICKS_CONFIG_PROFILE environment variables, but only the PAT Authentication works at the moment. If you need more authentication methods, please fork this GitHub repository and send pull request with the feature suggestion.

Example of overriding authentication profile. Look at databricks auth profiles to know which ones are working.

client <- DatabricksClient(profile="your-cli-profile")

Databricks SDK for R comes with all public workspace-level API and is consistent with Databricks SDK for Python, Databricks SDK for Go, and Databricks SDK for Java. Databricks SDK for R does not expose account-level API and you're recommended to use Go, Python, or Java SDK to build an account-level automation.

library(dplyr)
library(databricks)
client <- DatabricksClient()
running <- list_clusters(client) %>% filter(state == 'RUNNING')
context <- create_command_execution_and_wait(client, cluster_id=running$cluster_id, language='python')
res <- execute_command_and_wait(client, cluster_id=running$cluster_id, context_id=context$id, language='sql', command='show tables')
res

All list methods (and those, which return any list of results), do consistently return a data.frame of all entries from all pages, regardless of the underlying implementation.

list_clusters(client)[1:10,c("cluster_id", "cluster_name", "state")]
#              cluster_id                                      cluster_name      state
# 1  1109-110110-kjfoeopq                              DEFAULT Test Cluster TERMINATED
# 2  0110-221212-oqqpodoa                               GO_SDK Test Cluster TERMINATED
# 3  1109-012301-qlwlwqpq                               BRICKS Test Cluster TERMINATED
# 4  1109-110012-qpwoepqq                               VSCODE Test Cluster TERMINATED

All long-running operations do poll Databricks backend until the entity reaches desired state:

create_cluster_and_wait(client, spark_version = "12.x-snapshot-scala2.12", cluster_name = "r-sdk-cluster", num_workers = 1, autotermination_minutes=20, node_type_id="i3.xlarge")
# PENDING: Finding instances for new nodes, acquiring more instances if necessary

API clients for all services are generated from specification files that are synchronized from the main platform. Databricks may have minor documented backward-incompatible changes, such as renaming the methods or some type names to bring more consistency.
