Databricks

I would like to create the directory develop under Repos as part of the script, then link it to github and update it? How can I do this?

I have a large stream of data read from Confluent Kafka, 500+ millions of row. When I initialize the stream I cannot control the batch sizes that are read.I've tried setting options on the readstream - maxBytesPerTrigger, maxOffsetsPerTrigger, fetc...
