Hello Experts,Is there any API in databricks that allows to write the data in the Databricks tables. I would like to send small size Logs information to Databricks tables from other service. What are my options?Thank you very much.
and what about use the jdbc/odbc driver, either programatically or using a tool like dbeaver?
Any Idea why GitCopiot is not available in Azure Databricks, though it supports Github?
That is true (this is not an answer but a comment) vscode is supported. But vscode is not integrating with notebook on aws. When will this feature be available?
If Yes, how is order ensured? For example, let's say there are a number of CDC change files that are uploaded to a directory over time. If a table were to be created using the cloudFiles source, in what order would those files be processed?
Hi, Is there any new development in terms of ensuring ordering of the files in autoloader?
