Seems positioned to compete with Azure Data Explorer (MSFT's log/time series optimized service). I know Azure runs a lot of services on top of Data Explorer (previously called Kusto) I wonder if this is a true internal battle tested product or a me-too offering.

I use Kusto daily and it is by far my favorite dev tool. It's incredibly fast and actually fun to use. I'm interested to compare it to Timeseries.

Kusto is still the name of the query language and the desktop application (Kusto.Explorer), the service was just renamed to Azure Data Explorer.

Kusto is architecturally closer to Dremel (or BigQuery). It's a columnar compressed datastore with a nice query language. Not the most efficient way to store and query timeseries data though.

Back then (internally) we actually had a lot of issues with ingesting and querying time series data at scale.

I might be mistaken but wouldn't Data Explorer be more similar to AWS CloudWatch which has been around for a long time.

Azure Data Explorer/ Kusto is more of a database that is optimized for the log use case than a service. There is a front end tool and a lot of the use-cases are around log management, but it is database you can do general SQL or KQL things with. Time series is one of the core use-cases for it also but it has less marketing around it.

Sounds more like AWS CloudWatch Log Insights launched yesterday.
