             Summary: Caching take lot of time
                 Key: HUDI-1232
                 URL: https://issues.apache.org/jira/browse/HUDI-1232
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Selvaraj periyasamy
         Attachments: log1.txt

I am using Hudi 0.5.0.  

 

Issue 1) I have source 15 different transaction source tables written using 
COPY_ON_WRITE and all of them are partitioned by transaction_day, 
transaction_hour. Eat one of them are having more than 6 month data.  I need to 
join all of them and few of the tables would have to looked back up to 6 months 
 for join condition. When I do the join and execute, I see the attached logs 
rolling for longer time. Say example for one table to list all the files, it 
takes more than 5 mins for listing down the files before initiating join.  and 
it is happening in sequential flow. Wen I had to join 6 months data from two 
different tables, it easily takes more than 10 mins to list the file. I have 
grepped some the lines and attached. File name is log1.txt .

 

Issue 2)  After above joining all 15 tables , am writing then into another huh 
target table called trr.  The other slowness I am seeing is that, as the number 
of partitions is growing in trr table, I see below logs rolling for all 
individual partitions even though my write is on only couple of partitions  and 
it takes unto 4 to 5  mins. I pasted only few of them alone. I am wondering , 
in future , I would ave 3 years worth of data, and write will be very slow 
every time I write into only couple of partitions.
