We are trying to investigate how we can trigger a Sisense data model (schema) refresh from the API. This call would be made after a data pipeline schema change. We’ll need the calls to make to "Refresh Schema" how it is done in the UI.

It’d be nice to save the layout with the .smodel file. That way, I can group related tables together. Maybe also allow comments/colours/tags to show up on the UI. E.g. I could put payroll-database dimensions on one side in blue, operational-database dimensions in orange on the other, and facts in the middle. ... View more

I have a data model with lots of tables (more than 30). That makes the UI painfully slow, e.g. when editing relationships. I think the reason is that it’s calculating where to place them on the screen. I’d like to request an alternative, crude interface that doesn’t slow down for lots of tables. Or make it work for lots of tables – e.g. do the positioning calculations when first opening, but not each time I resize or click on something. ... View more

There are many scenarios where a model contains data for many distinct groups, such as customers, and you want viewers to only have access to the data that pertains to their specific customer. This is easily implemented with row level security, when there is a data column that uniquely identifies each customer. But what if you have a requirement that certain types of viewers should see all columns of data per row, while others should not have access to certain columns? Here is an approach that can be implemented right out of the box in Sisense. The one prerequisite is that any table that contains sensitive data must have a column that uniquely identifies every row, i.e. a primary key column. For every table that contains sensitive data in certain columns, create a new table that contains the original table's primary key column, a binary "switch" column with a name like [Access Allowed] and a column for each of the sensitive columns. Remove the sensitive columns from the original table. Modify the import query to load only the non-sensitive columns in the original table. Modify the import query to load the new table with the primary key and sensitive columns of the original table twice, once with [Access Allowed] set to 1 and the second time with 0 and blank (or null) for all the sensitive columns. Associate the new table to the original table by primary key column Create a dimension table for secure access with the column [Access Allowed]. One row with value 0, one row with value 1. Associate the dimension table with the sensitive data table by the [Access Allowed] column. Set up a data security rule on this column, assigning the secure user group to value 1 and the general group to value 0 If there is a hierarchy greater than two levels of column-level data security, this model can be extended to create additional one-to-one related tables to the original table. ...

Right now, if you're making significant changes to an existing cube, the only way to verify that you haven't broken something is to actually do a build. I'd like a Verify or Validate button, next to the Build button, that would do the initial steps of the build process and then stop.  For example, determine if the metadata in the table can actually be retrieved from the underlying data source.  Or checking datatype mismatches in existing joins.  And so on.  Just leave out the last step where you actually retrieve the full data set and then build the cube. This would save time during the development process. ... View more

Hello There, We need to create a data model with 2 different data sources . One databricks live and another one is an excel file with some additional data .

We need a view that shows us which dashboards are dependent on which table in the datamodel. We want to remove some tables, but because we have many dashboards we don't know where exactly that table data is being used so it's very risky to change/delete tables. The depedency granularity of the data model is good but not enough. ... View more

When replacing a server, or testing an upgrade, we often find our clients taking a backup of their Sisense database and restoring it to another server. After updating the server identity in the mongodb, it's pretty much ready to go. However, use dashboards all reference the old server and have to be updated. This is a manual process that the users themselves one dashboard and data source at time. An administrator cannot easily do that work on their behalf. Acknowledging that there is a replace_datasource API call that allows you to apply a new server and data source to a single dashboard, I would love an easier a way to update just the server across all dashboards. ...

Hello, Currently the number of queries running in parallel during an EC build is set at the server level. With setting "Build / Base Table Max Threads" (4 by default). The optimised number of simultaneous queries is very much dependant on the context of the EC. For instance, an EC with 4 differents date source is more likely to accept a high number of simultaneous queries (spread over the 4 data sources), than an EC with only one data source. Therefore, I would like to suggest to make this setting per cube instead of at the server level. An alternative would be to have this setting at the Data Group level. Thank you and best regards, Franck   ... View more

When you export a datamodel to a .smodel file, the file includes connection information (server name, password, etc.). I would like an option to exclude that information when I click export. The export dialog already offers check boxes for Data Security, Scope Configuration, etc.; this feature could be just another one that says "Connection Information". Ideally, I'd like it to exclude the connection information by default, so users are forced to explicitly ask to include it, which will remind them to consider the file as sensitive. But I understand if you don't want to change default behaviour that other users are used to. When you import a model that has had this information removed, the import should let you to enter new connection information, or leave it as placeholders like Server=0.0.0.0 and password=Password so you can enter the information after importing. Sisense GIT already removes this information; this feature could work in a similar way. You could even deliberately make GIT's "non-tracked entities" all appear on the list of export options.

Hi, I have gone through your connection update process for live models. But As I discussed with sisense team, they don't have any single API for updating connection. As per current scenario we need to follow multiple steps like below:- 1. Get table by: GET /datamodels/datamodelId/schema/datasets/datasetId/tables/tableId. response => tableResult 2. Override table by PATCH /datamodels/datamodelId/schema/datasets/datasetId/tables/tableId} where body = tableResult from the step 1. Only after performing the above steps, you can use PATCH/datamodels?/datamodelId?/schema?/datasets?/datasetId to update the schema for this dataset. So I just want to proposed one idea here that we can use multiple option here like below:- 1. We can provide any Key Vault connectivity for each model where we can store our connection details and we can use them for our model connections. 2. We also can provide a single API where our connection can we updated for all relevant objects & model it self. ... View more

Summary: Live Model slow, can be fixed by prioritising a filter I use a Live Model to return info about a few records from a big dataset. One filter should efficiently narrow the big dataset down. But the server sometimes applies other filters or joins first, making it unusably slow. I want an option to tell the Live Model to fetch the important filter's items first, and then write those items into the filtering clause when writing the main query. That will cause the server to correctly discover that applying the important filter first is the most efficient query plan.   Details (I'm querying SQL Server, but I suspect other sources would also benefit.) Sisense documentation says "Analytical Engine inserts filtering clauses into the innermost SQL statement. This means that filtering is the first operation performed". Sometimes that helps performance. But it depends on the source server. If you apply multiple filters or joins, the server may decide to perform a less efficient one first, or it may parallelise. In my case, my query went from a few seconds to over an hour depending on the server's choice.  The problem is that the server can't estimate the cardinality of the "filtering clauses" entered by Sisense. For example: The server doesn't know that my "dimCustomer.[Customer Name] = 'Joe Bloggs'" filter returns only 100 rows from my fact table, whereas "dimDateTime.FiscalYear = 2022" returns 100,000,000 rows from the fact table. There is a solution. Instead of "Where Fact.[Customer ID] In (Select [Customer ID] From dimCustomer Where [Customer Name] = 'Joe Bloggs')", Sisense should first run the query Select [Customer ID]... query to find that Joe's ID is 5. Then put the result into the filtering clause, i.e. "Where Fact.[Customer ID] IN (5)". For a hardcoded ID like that, the server can estimate the cardinality, so it sees that filtering on [Customer ID] first will be more efficient that other query plans. Sisense mustn't just do that for all filters. If it tries prefetching "dimDateTime.FiscalYear = 2022", that'll return all 31,536,000 seconds, and then pass that back in the query as "Where Fact.DateTimeID IN (...)".  Solution: The solution I request is: Allow the Live Model developer to set a "Prefetch Filter Items" flag on a field. If it is set, when a widget or dashboard filters that field, then Sisense first creates a query "Select dimSomething.[Relationship column] From dimSomething.FieldWithPrioritisedFilter". Then, when building the main query, change the "filtering clauses" to be "Where Fact.[Relationship column] IN (<put prefetched values here>)". Reference: For reference: https://docs.sisense.com/main/SisenseLinux/analytical-engine-overview.htm: Analytical Engine inserts filtering clauses into the innermost SQL statement. This means that filtering is the first operation performed, minimizing the number of rows that need to be scanned in order to process the query. Complex filters, such as top ranking and filter on measure are significantly improved as a result. Proof of concept: Build a Live Model. FactA joins to DimB on ID_B and to DimC on ID_C. The source is SQL Server. In SQL Server, all three tables have millions of rows, and the FactA has foreign keys to DimB and DimC. DimB.Name has a unique name for each row. DimC.Type is 1 for half the rows, and 0 for half the rows. Create a widget that filters for DimB.Name=<some name> and DimC.Type=1. Use SQL Profiler to find the query your Live Model runs. Run the query; it should take over a minute or time out. Then change the "Where FactA.ID_B IN (Select ID_B From DimB Where DimB.Name IN ('<some name>'))" to instead be "Where FactA.ID_B IN (<copy paste the ID of <some name> here>)". It should run much quicker. The original query might run quickly without change, depending on server settings; if so, mess about with more complicated joins or ask me. In my setting key queries were reliably slow. ... View more

Hi, I have issue with setting two date dimensions in dashboard. The goal I want to achieve is to have a history of records, which are also have it's own date dimension. You can download model and dashboard. I would like to have difference in growth ower selected period for defined dates. For example 2 days ago I sold a car for 1000, and yesterday the proce have changed to 1500. The sale date is for today. So the growth over 2 days is 1500, and for 1 day 500. Additionally i would like to compare those values to previous year, and go back with both date dimensions. Tricky part is also, that if there is not sale for this year, PastYear() wont count prior year. I tried to play around with filtered measure plugin, however it doesn't give me exactly what i want. Do you have any suggestions how can I approach such data and 2 date dimensions? Thanks 🙂 ... View more

When viewing a datamodel, there's a button to view as "List" instead of "Diagram". I sometimes use that when I need to methodically check each table.
