Kusto/Azure Data Explorer Client Query Limits
Hi tessaw ,
What is the error message?
What connection mode have you adopted? Import or Direct Query?
It may be an error caused by a limitation in Power BI.
Best regards,

Hi v-lionel-msft , the actual error in PowerBI itself was not very descriptive, it only said that some of the rows failed to refresh/load. Only once I ran the query in Kusto/Azure Data Explorer itself did I get a descriptive error message which led me to the article I listed in the original post. Specifically, the error message was:
"The Kusto DataEngine has failed to execute a query: 'Query result set has exceeded the internal data size limit 67108864 (E_QUERY_RESULT_SET_TOO_LARGE).'"- v-lionel-msft6 years agoCommunity Support
Hi tessaw ,
Considerations and limitations
Power BI also has restrictions on connected data.
