Thank you in advance,
I reindexed 5 Gb data from 5.6 ES cluster to 7.6 ES cluster. The data size decreased to 2.7 Gb, But the document count is the same. Can I know why this is happening?
The only difference between 5.6 ES cluster and 7.6 ES cluster is mapping, they are as follows.
There are no types in 7.6 ES cluster. (We are having single type mapping in 5.6 ES cluster so I removed type name in the mapping )
For the time zone, I am using XXX in 7.6 ES cluster instead of Z in 5.6 ES cluster
Instead of integer and long in 5.6 ES cluster, we are using double in 7.6 es cluster.
