Hi @Witold 

After trying 
table = (spark.read
.format("jdbc")
.option("url", "<jdbc-url>")
.option("dbtable", "<table-name>")
.option("user", "<username>")
.option("password", "<password>")
.option("fetchSize", "1000") -- to 50000
.load()
)

job is taking lots of time  and not even reading 10 million records.
