I have defined an index template with 4 shards, ILM policy and fields mapping. When I execute my Transform, every thing defined in the template is applied except the number of shards. My ElasticSearch version is 7.6.2. I know that Transform is in beta version on 7.6.2, is this a bug or an expected thing ?
By the way, my actual workaround is to create manually my index with the wanted number of shards before executing the Transform.
Please use the workaround to create the destination index with a higher shard count.
If you upgrade to 7.7+ the transforms preview endpoint will also return the generated mappings, making it easier to see the deduced mappings and index settings. You then have the option to override by manually creating the index instead.
