Hello everyone,I am trying to determine the appropriate cluster specifications/sizing for my workload:Run a PySpark task to transform a batch of input avro files to parquet files and create or re-create persistent views on these parquet files. This t...
If the data is 100MB, then I'd try a single node cluster, which will be the smallest and least expensive. You'll have more than enough memory to store it all. You can automate this and use a jobs cluster.
Attempting to install SparkR to the cluster and successfully installed other packages such as tidyverse via CRAN. The error is copied below, any help you can provide is greatly appreciated!Databricks runtime 10.4 LTSLibrary installation attempted on ...
Hi @Ross Hamilton​ ,I believe SparkR comes inbuilt with Databricks RStudio and you don't have to install it explicitly. You can directly import it with library(SparkR) and it works for you from your above comment.The error message you see could be re...
I'd like to know what is the design pattern for ingesting data via http API request. The pattern needs use multi-hop architecture. Do we need ingest JSON output to cloud storage first (not bronze layer), then use auto loader to process data further? ...
The API -> Cloud Storage -> Delta is more suitable approach.Auto Loader helps not to lose any data (it keeps track of discovered files in the checkpoint location using RocksDB to provide exactly-once ingestion guarantees), enables schema inference ev...
I have data like, below and when reading as CSV, I don't want to consider comma when its within the quotes even if the quotes are not immediate to the separator (like record #2). 1 and 3 records are good if we use separator, but failing on 2nd record...
Hi, I think you can use this option for the csvReadeespark.read.options(header = True, sep = ",", unescapedQuoteHandling = "BACK_TO_DELIMITER").csv("your_file.csv")especially the unescapedQuoteHandling. You can search for the other options at this l...

It seems that .option("databaseName", "test") is redundant here as you need to include the db name in the url.Please verify that you use a connector compatible to your cluster's Spark version : Apache Spark connector: SQL Server & Azure SQL
Folks , when I want to push data to snowflake I need to use a stage for files before copying data over. However, when I utilise the net.snowflake.spark.snowflake.Utils library and do a spark.write as in...spark.read.format("csv") .option("header", ...
Yes it uses a temporary stage. should have just looked in snowflake history
