pyspark - Inserting and Deleting data in a Spark Dataframe -


i have pyspark dataframe input_dataframe shown below:

**cust_id**   **source_id**     **value**    10              11          test_value    10              12          test_value2

i have dataframe delta_dataframe have updated records input_dataframe , new records shown below:

**cust_id**   **source_id**     **value**    10              11          update_value    10              15          new_value2

in both dataframe, primary key combination of cust_id , source_id.

i have generate new dataframe output_dataframe, have records input_dataframe updated records delta_dataframe, final dataframe below:

**cust_id**   **source_id**     **value**    10              11          update_value    10              12          test_value2    10              15          new_value2

can please suggest me, how can achieve in pyspark. appreciated on this.

subtract 2 dataframes based on primary key. make inner join of output input_dataframe. take uion of delta_dataframe. proper output.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
