Alright, we've implemented a workaround for this, and so far it's been working very well:First, we created a reusable notebook to wait until Hive has been initialized (see code below).We then execute this notebook using the %run command at the top of...
I am trying to create a sqlite database in databricks and add a few tables to it. Ultimately, I want to export this using Azure. Is this possible?
@Hubert Dudek We currently have a process in place that reads in a SQLite file. We recently transitioned to using Databricks. We were hoping to be able to create a SQLite file so we didn't have to alter the current process we have in place.

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...
Is it possible to have a folder or database with a database in Azure Databricks? I know you can use the "create database if not exists xxx" to get a database, but I want to have folders within that database where I can put tables.
The default location of a database will be in the /user/hive/warehouse/<databasename.db>. Irrespective of the location of the database the tables in the database can have different locations and they can be specified at the time of creation. Databas...
