Hello
Hopefully a quick and easy question;
Does having fewer shards per index equate to less disk space being used?
When I set off on my elastic adventure a year ago I used the default 5 shards per index. I now have 4 different index 'types'(?), each holding data for 30 days in a daily index, so that was quite a lot of shards for my poor little elastic box. (30 * 4 * 5), and it was taking about 30 minutes to restart as it was allocating all the shards!
I've changed the index template used to just use 1 shard per index now, and elastic seems to be much faster
As a side effect I have noticed in the xpack monitoring my Data value seems to have dropped. When I had 5 shards it was around 30GB, now I am around 25GB. (approx 60,000,000 documents, seems to be about what I usually have).
Is that what would be expected, or do I need to hunt around for where I have lost 5GB of data...
Thanks!
