I ran a query "Select * from fact_Orders". This presented a lot of garbage, The correct column headers, but the contents were extremely random, e.g. blanks in the key column, VAT rates of 12282384234E-45 . When I export to CSV , it presents fi...
I got a notebook running on DBR 12.2 with the following R code: install.packages("microbenchmark") install.packages("furrr") library(microbenchmark) library(tidyverse) # example tibble df_test <- tibble(id = 1:100000, street_raw = rep("Bahnhofs...
In the scala notebook of databricks, I created a temporary function with a certain Jar and class name. Then I want to update the Jar. But without restart the context, I can not reload the new Jar, the temporary function always reuses the old classes....
Hi I have a structured streaming job that reads from a delta table "A" and pushes to another delta table "B".A Schema - group_key, id, timestamp, valueB Schema - group_key, watermark_timestamp, derived_valueOne requirement is that i need to get the m...
I have a question regarding streaming with CDC.We currently have a delta table where CDC is not yet enabled, and its the source for other following streams that read from that table.To catch the changes for a new usecase, we need to enable CDC on tha...
We have SQL database. Database is designed in star schema. We are migrating data from SQL to databricks. There are cubes designed using SSAS. These cubes are used for end users in excel for analysis purpose. We are now looking for solution for:1) Can...
Databricks itself does not deliver semantic models like SSAS cubes. So Databricks cannot migrate them because there is nothing to migrate to.However, there are some options:- use of PowerBI instead of SSAS (there might even be a migrate option?). W...
Hi,I would like to know what you think about using the Delta Live Tables when the source for this pipeline is not incremental. What I mean by that is suppose that the data provider creates for me a new folder with files each time it has update to the...
When dealing with B2B data building, the process of updating and managing your data can present unique challenges. Since your data updates involve new folders with files and you need to process the entire new folder, the concept of incremental proces...
Is there api call to set "Table access control" workspace config ?
Faciing the same issue, tried to fetch the current value via /api/2.0/workspace-conf?keys=enableTableAccessControlUnfortunately this is returning a 400 { "error_code": "BAD_REQUEST", "message": "Invalid keys: [\"enableTableAccessControl\"]"}
Could you please provide me an idea how I can start reprocessing of my data? Imagine I have a folder in adls gen2 "/test" with binaryFiles. They already processed with current pipeline. I want to reprocess the data + continue receive new data. What t...
@Eldar_Dragomir In order to re-process the data, we have to change the checkpoint directory. This will start processing the files from the beginning. You can use cloudFiles.maxFilesPerTrigger, to limit the number of files getting processed per micro-...
I am trying to run a notebook which reads some of its variables from and external notebook (I used %run command for that purpose), but it keeps giving me error that these variables are not defined. These sequences of notebooks run perfectly fine on a...
I think the issue here is the variable is not created until a value is assigned to it. So, you may need to assign a value to get_sql_schema
I have to 2 questions about elapsed job runtimes. The same Scoring notebook is run 3 times as 3 Jobs. The jobs are identical, same PetaStorm code, CPU cluster config ( not Spot cluster) and data but have varying elapsed runtimes. Elapsed runtimes...
Hi @NathanLaw, Could you please confirm, if you have set any parameters for the best model? Is this stop after running some epochs if there is no improvement in the model performance?
Hi all,We are planning to develop an Autoloader based DLT Pipeline that needs to beDeployable via a CI/CD PipelineObservableCan somebody please point me to source-code that we can start with a firm foundation instead of falling into a newbie-pattern ...
Hi @Sanjay_AMP Delta Live Tables and AutoLoader can be used together to incrementally ingest data from cloud object storage.• Python code example: - Define a table called "customers" that reads data from a CSV file in cloud object storage. - Define a...
Hi databricks/spark experts!I have a piece on pandas-based 3rd party code that I need to execute as a part of a bigger spark pipeline. By nature, pandas-based code is executed on driver node. I ran into out of memory problems and started exploring th...
Hi @wojciech_jakubo 1. JVM memory will not be utilized for python related activities. 2. In the image we could only see the storage memory. We also have execution memory which would also be the same. Hence I came up with the executor memory to be of ...
Hey, guys.I have a question, so, I have databricks jobs in workflow that are linked to my databricks repo, which contains the necessary scripts for one or another job. That is, the job is linked to the databricks repo.The main code is developed in gi...
Does the user which the API token is generated from has the git credential configured for the git repo ?If not, you can follow the steps here : https://docs.databricks.com/en/repos/get-access-tokens-from-git-provider.html
Hello,I'm facing a problem with big tarballs to decompress and to fit in memory I had to limit Spark processing too many files at the same time so I changed the following property on my 8 cores VMs cluster:spark.task.cpus 4 This setting is the thresh...
Hi @Thor, Spark does not offer the capability to dynamically modify configuration settings, such as spark.task.cpus, for individual stages or transformations while the application is running. Once a configuration property is set for a Spark applicati...
