I am confused about what exactly is the int ReadAhead Limit in mark(int readAheadLimit).

In a huge file if the buffer is marked what should be its value ?

Thanks

  • It should be how far you might want to wind back. It is how much it will buffer so you can wind back that much. – Peter Lawrey Jul 24 '14 at 02:59

  • is it in bytes ? For Huge files, if I mark back 1000 records, then how will I know the exact value ? Does it has any system performance issues ? – Noman K Jul 24 '14 at 03:02
