I have been trying to create a new cluster to use and multiple attempts have gotten stuck in pending: "Finding instances for new nodes, acquiring more instances if necessary" until they time out. Up to today I have had no problems creating clusters ...
This is typically a cloud provider issue. You can file a support ticket if the issue persists.
I’m trying to use LSH approxSimilarityJoin on a dataset with ~25k 300-d vectors of floats. It gets stuck and eventually fails with ’Slave lost’ error. The size of cluster and memory are likely not a problem, the failure happens even with 16 nodes, 1...
Use a PandasUDF with Arrow enabled. They are improved in Spark 3, but you can use them in Spark 2.4.5.
Hello people,I'm trying to build a facial recognition application, and I have a working API, that takes in an image of a face and spits out a vector that encodes it. I need to run this on a million faces, store them in a db and when the system goes o...
You could do this with Spark storing in parquet/Delta. For each face you would write out a record with a column for metadata, a column for the encoded vector array, and other columns for hashing. You could use a PandasUDF to do the distributed dista...

@austiamel47, Yes, you can certainly do this. Delta Lake is designed to be competitive with traditional data warehouses and with some tuning can power low-latency dashboards.https://databricks.com/glossary/data-lakehouse
Yes. A new workspace would need to be deployed because Azure allows people to change the vnet cidr but it requires you to remove all the vnet resources first. This includes the Databricks deployment, therefore, this is an Azure restriction on how VNE...

Hi everybody! Is it possible to use one job cluster for multiple tasks using new task orchestration tool? If so then please tell how. If it's impossible then this new tool looks useless Regards, Daniil.
Databricks team, are there any news about it?
The the regular version of databricks, the dbfs is mounted at /dbfs. This does not seem to be the case with community edition. I am seeking more details.
If you are using DBR 7.x. or newer versions the dbfs is disabled. You have to use dbutils.fs.cp commands as a workaround.
I want to use the VS Code IDE to edit/write/work on jupyter notebooks but have the code run off of the databricks cluster. Does anyone know of a way for me to force the jupyter notebook server on VS Code to point towards the databricks cluster and e...
