            Scala: in where clause how to get column string value and split, and intersect against another array?

            I have a dataframe where one column is ; separated strings, e.g. "str1;str2;str3;str4", I also have another static list "strx;stry;strz", the goal is to split the column string value and check if the split array has any intersection with the static list, and keep that row

            It seems you're mixing up Spark's split method for Columns with Scala's split for Strings. Please see example below for how the two different split methods are used. Method array_intersect is for intersecting the split Array column with the split element-filter string.

            This seems like a bug introduced by a bug fix in this ticket. The result was wrong for outer joins. Hence the need to add a Project node (packing of the struct) before the Join node.

            Java Spark Dataset MapFunction - Task not serializable without any reference to class
            Asked 2021-Jun-15 at 11:58

            I have a following class that reads csv data into Spark's Dataset. Everything works fine if I just simply read and return the data.

            However, if I apply a MapFunction to the data before returning from function, I get

            Exception in thread "main" org.apache.spark.SparkException: Task not serializable

            Caused by: java.io.NotSerializableException: com.Workflow.

            I know Spark's working and its need to serialize objects for distributed processing, however, I'm NOT using any reference to Workflow class in my mapping logic. I'm not calling any Workflow class function in my mapping logic. So why is Spark trying to serialize Workflow class? Any help will be appreciated.

It is planned that this feature will be available in Airflow 2.1.1. For more information, see: Adding extra requirements for build and runtime of the PROD image.

            Does the number of kafka partitions increase the speed of Spark writing to kafka?
            Asked 2021-Jun-14 at 14:31

            When reading, Spark have a mapping 1:1 to kafka partitions, so, with more partitions we can leverage more parellelism to our job.

            But does it apply when Spark is writing in kafka ? Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition ?

            ...

            ANSWER

            Answered 2021-Jun-14 at 14:31

            Yes.

            If your topic has 1 partition means it is in one broker. So, If you increase producer rate for the topic, then that broker becomes busy. But if you have multiple partitions, your Kafka cluster shared those partitions into different brokers and those production rate shared within multiple brokers. So, Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition.

            This not only production rate. In Kafka brokers, There is multiple processes like compactions, compressions, segmentations etc... So with number of messages, that work load becomes high. But with multiple partitions in multiple brokers, it will be distributed.

            However, you don’t necessarily want to use more partitions than needed because increasing partition count simultaneously increases the number of open server files and leads to increased replication latency.

            from kafka documentation

            Distribution The partitions of the log are distributed over the servers in the Kafka cluster with each server handling data and requests for a share of the partitions. Each partition is replicated across a configurable number of servers for fault tolerance. Each partition has one server which acts as the "leader" and zero or more servers which act as "followers". The leader handles all read and write requests for the partition while the followers passively replicate the leader. If the leader fails, one of the followers will automatically become the new leader. Each server acts as a leader for some of its partitions and a follower for others so load is well balanced within the cluster.
