i have an ELK(Elasticsearch-Kibana) stack wherein the elasticsearch node
has the default shard value of 5. Logs are pushed to it in logstash format(
logstash-YYYY.MM.DD), which- correct me if i am wrong- are indexed
date-wise.
Since i cannot change the shard count of an existing index without
reindexing, i want to increase the number of shards to 8 when _the next
index is created_. i figured that the ES-API allows on-the-fly persistent
changes.
How do i go about doing this?

Hey,
if you use logstash, you could change the default index template to use 8
shards. See
