By default SHS uses spark.history.fs.numReplayThreads = 25% of avaliable cores (Number of threads that will be used by history server to process event logs)How can we increase the number of cores for Spark History Server ?

There is a "Danger zone" appearing in the Github indicating that the repositories I share on Databricks should be Suspended and possibly that Databricks should be uninstalled. This may be something standard in Github. Has anyone run across it?
It's not telling you that you should do these things. It's telling you that you may break stuff by doing these things. Yes the "Danger Zone" is a thing on Github, it tries to warn you before you do things like click to delete a repo.

More specifically: langchain releases a new update every few days, and it is likely that you are using code or a library that needs a later version of langchain than you have (or, perhaps, a later version that removed whatever part of langchain you r...
I am running a databricks notebook. While running, i only see one task on one worker getting started. My cluster has min 6 workers but seems like they are not getting used.I am performing a read operation from Cosmos DB.Can someone please help me her...
If your code does not use Spark, it will not use any machines except the driver. If you're using Spark but your source data that you operate on has 1 partition, there will be only 1 task. Hard to say more without knowing what you are doing in more de...
Some questions related to fine-tuning and the MIT License, I read the MIT license but still confusing about some points.If I fine-tune the Dolly-v2 model, say using LoRA and my own dataset,Do I "own" the fine-tuned model?Am I allow to change the name...
I am not sure I agree with the discussion so far. While none of here are lawyers, I think it's fairly straightforward to reason about the licensing.You have created a combined, derivative work from the Dolly weights in this case. You have copyright i...

Currently, in our company we are using ADF+DATABRICKS for all batch integration. Using ADF first data is copied to ADLS gen 2 (from different sources like on prem servers, ftp solution file sharing, etc), then it is reformatted to csv and it is copie...
@-werners- Is there any benefit of doing the extract part in databricks itself? Unlike our current architecture, where we first load to adls using adf. I guess it is worth doing all end to end using databricks if there is better processing, lower lat...
