Do whatever you want.
First I suggest to thinking.
What will the result if you
- decrease the index numbers
- set the high watermark to 5 gb? (spend 10 minutes with this question, based on your screens, you will open a new topic at the community with elatic cluster red again OR no disk space left)
- (you)r client goes wrong, and send +1 GB data every day
Do a fast research for this questions:
- connection between shards and indices
- elasticsearch no disk space left
- elasticsearch suggested shard size
After you find the answers to your questions, please let us know.
yes.
