Optimizing max records inORC files

[#1]

Hello,

I have a process that will push rows to an external table, it shall push around 500M cdr per day.

the external tables is using orc file with the following config:

• Max Records: 10K
• Compression Type: snappy
• Stripe Size: 67,108,864
• Row index Stride: 10K
• Bloom Filter Columns: NA
• False Positive Probability of Bloom Filter Columns: 0.05

what is the max records i go to while writing the files? to get the advantage of minimizing the number of generated files

And the other params used above, are the default per the product.. When should i tune these parameters?
