Hi Guys, Hope you all are doing good. In my ES, I am facing java heap memory error, while indexing just 20k records. Even I have increasesd the heap memory size in ES bat file. can anyone of you suggest me what all changesges I need to do for this. Or ES has certain restricition on windows machine for indexing the data. I faced this issue even for 6k records also. Any help/pointers will help me. Thanks a lot.

How big is each document? What is the total size of the 20k records? You might have to update with smaller batches. -- Ivan On Tue, May 13, 2014 at 10:28 PM, dharmendra pratap singh \< [dharmendra0393@gmail.com](mailto:dharmendra0393@gmail.com)\> wrote: > Hi Guys, > Hope you all are doing good. > > In my ES, I am facing java heap memory error, while indexing just 20k > records. > > Even I have increasesd the heap memory size in ES bat file. can anyone of > you suggest me what all changesges I need to do for this.
