Hello, I need few clarifications for the following questions related to sequenceFiles
1. I have a bunch of sequence file. Each file has 8 keys and corresponding values. The values are float array bytes, and key is a name which is a string. Now, storing these smaller files and processing is not efficient as there can be milliions of such files. Hence, I am thinking of creating one sequence file out of such large number of files. Is it possible? I read in the literature that there are ways to merge sequence files. My question is that if I merge large number of sequence files, how can I retrieve individual small sequence file in my map processes? 2. when I merge, it becomes a different sequence file altogether with keys merged? If this is the case, my keys will be same for all the files. How it will be handled? Will there be any problem here? 3. Is it possible to append keys and values to existing sequence file? regards rab
