editUpdates now detect_noop by default
editWe’ve switched the default value of the detect_noop option from false to
true. This means that Elasticsearch will ignore updates that don’t change
source unless you explicitly set "detect_noop": false. detect_noop was
always computationally cheap compared to the expense of the update which can be
thought of as a delete operation followed by an index operation.
