David, Can you help me reconcile this thread, with what we discussed here: > [@Are contents of a bucket held in the same shard?](https://discuss.elastic.co/t/are-contents-of-a-bucket-held-in-the-same-shard/141059): > > We are evaluating using buckets to keep data by user account in a single bucket (e.g. the bucket becomes the "accountid" container, holding all documents for that account) The question has arisen: If we have a 20 or 100 shard index, will a given bucket always be kept within a single shard? If not, how many shards will it span? On that thread, it sounded like I could define a bucket up front (for a given account), and then documents added to that bucket would be held together on a single shard. Please help me understand all the way. Thanks! --- _[View the full topic](https://discuss.elastic.co/t/are-buckets-persistent/143780)._
