Public sample Logs table to demonstrate Kusto - azure-log-analytics

The kusto tutorial references a Logs table. Is this data available publicly somewhere so as to try kusto out on a very large data store?

The samples in the tutorial which reference the StormEvents table can be run against the Samples database in the Help cluster: https://dataexplorer.azure.com/clusters/help/databases/Samples
Data sets used in other samples (such as those referencing the Logs table or the Events table) are not publicly available at this moment.

Usage Tracking in Azure synapse analytics

Can anyone share a Kusto query (KQL) that I can use in log analytics that would return some usage tracking stats?
I am trying to identify which "Views" and "Tables" are used the most. Also trying to find out who the power users are and commands/query that is run against the "Tables".
Any insights would be appreciated.
You can use below functions to gather the useage statics
DiagnosticMetricsExpand()
DiagnosticLogsExpand()
ActivityLogRecordsExpand()
And create target tables to store the function data to analyse the useage information.
Refer the Azure documentation for complete details https://learn.microsoft.com/en-us/azure/data-explorer/ingest-data-no-code?tabs=activity-logs

Can I audit access to a BigQuery dataset shared with external users?

I'm making a BigQuery dataset available to specific external users (meaning, they run their queries in the context of a private project) through dataset sharing. Is there any way to collect basic metrics regarding the use of the dataset, such as - which tables are being accessed?
This is doable through Google BigQuery audit logging. This tutorial provides step-by-step instructions for how to save the logs in a BQ dataset and query it for analysis.

SAP Cloud Foundry Trial and hanatrial Service HDI-Shared Plan

I'm using a trial account in SAP Cloud Platform and created an instance of the "hanatrial" service, witch is up and I can even query the public table "tables".
The service provide me, in the VCAP_SERVICES, two users: user and hdi_user.
Both appears to have the same privileges in the schema provided, and cannot create any data in any public table table nor create any tables inside the provided schema.
My question is: is it possible to create tables or a single table with the "hanatrial" service? I have been two days searching for an answer in the SAP documentation and in the Internet without having found an evidence that it is nor that it is not.
For those of you whom still wonder apparently Hanatrial has no suport for creating tables.

Is maprdb a document store or a key value store

I know that mapr db exposes OJAI interface to query using json documents and hbase api's using which we can create column families.
I want to know how does mapr db store data on file system, and what kind of queries are costly and what kind of queries are cheap (for which maprdb is really made for).
It would be really helpful if some one can give some guidelines on what basis should we create column families if we are using hbase api's to access maprdb.
Please share any references that can answer this question

Bigquery Python API: create table with comments

I'm currently creating sharded tables daily using the Python API.
Is there a way to add the comments for the table's columns when creating the table ? I couldn't see it in the doc but it might still be implemented.
Thanks in advance.
From the REST API for BigQuery documentation, tables.Insert takes a table resource, and in the schema.fields[].description property, you can put in a description.
