Hi soumil, please make a vedio on what is the threshold in terms of memory usage in disk/cache of an index & how to run elasticsearch in cluster mode in different machines

Hey Soumil, can we reindex by keeping first index as backup

[udayreddy]

Hi Can we split the existing record into two( EX app_name =A, B
I want to have the record as APP_NAme1=A and APP_Name2=B using re-indexing ?

Hi! Do you know if exist some way to reindex a index for new mapping automatically? I'm thinking in a python script. Do you know if this is possible? Thanks for the video.
