Re: Spark Explain Plan and Joins

I actually went through the sort-merge algorithm and found out that it compares the two values and actually resets the respective pointer to the last matched pointer and then goes on comparing and fetches the records. Could you please go through

Re: Spark Explain Plan and Joins

Yes correct because sort-merge can only work for equijoins. The point being that join columns are sortable in each DF. In a sort-merge join, the optimizer sorts the first DF by its join columns, sorts the second DF by its join columns, and then merges the intermediate result sets together. As

Structured Streaming + UDF - logic based on checking if a column is present in the Dataframe

Hello All, I'm using StructuredStreaming, and am trying to use UDF to parse each row. Here is the requirement: - we can get alerts of a particular KPI with type 'major' OR 'critical' - for a KPI, if we get alerts of type 'major' eg _major, and we have a critical alert as well _critical,

Re: Spark Explain Plan and Joins

From what I understood, you are asking whether sort-merge can be used in either of the conditions? If my understanding is correct then yes because it supports equi joins. Please correct me if I'm wrong. On Thu, Feb 24, 2022 at 1:49 AM Mich Talebzadeh wrote: > OK let me put this question to you

Hi Mich, Thanks for the link. I will go through it. I have two doubts regarding sort-merge join. 1) I came across one article where it mentioned that it is a better join technique since it doesn't have to scan the entire tables since the keys are sorted. If I have keys like 1,2,4,10 and other

Hi Gourav, Thanks for your time. I am worried about the distribution of data in case of a huge dataset file. Is Koalas still a better option to go ahead with? If yes, how can I use it with Glue ETL jobs? Do I have to pass some kind of external jars for it? Thanks, Sid On Wed, Feb 23, 2022 at

Hi, this looks like a very specific and exact problem in its scope. Do you think that you can load the data into panda dataframe and load it back to SPARK using PANDAS UDF? Koalas is now natively integrated with SPARK, try to see if you can use those features. Regards, Gourav On Wed, Feb 23,

Spark does do distributed ML, but not Tensorflow. Barrier execution mode is an element that things like Horovod uses. Not sure what you are getting at? Ray is not Spark. As I say -- Horovod does this already. The upside over TF distributed is that Spark sets up and manages the daemon processes
