Is there a new limitation in Elastic Cloud 8.x instances that prevents the use of index.mapping.total_fields.limit greater than 1024 in an index template? Seeing a deprecation issue “exceeds the automatic field expansion limit of [1024]“.
PUT /<index>/_settings
{
"index.mapping.total_fields.limit" : 2048
}
While you can increase the limit, the suggestion is it's usually not advisable on performance grounds. Too many fields suggest there would be a benefit in adjusting mapping and/or indexing to reduce this.
