Hi there, I noticed that in Java bulk API, some parameters can be set can on both per-batch-request level and per-operation level, e.g. the consistency level parameter: BulkRequestBuilder#setConsistencyLevel v.s IndexRequestBuilder. setConsistencyLevel. What if the parameter has different values between these two level? Will the per-operation one override the per-batch-request one?

When using bulk indexing, the parameters in the single index request are not used. In order to stay consistent in the API, the bulk request provides some methods of the same name as the single indexing action again. But this is now for controlling the internal bulk execution that spans a number of indexing operation. It is not implemented as a mere sequence of indexing actions, but as a new distributed asynchronous action, with dedicated "bulk write consistency". Regarding consistency level, the execution for a single indexing operation is simple: first, the index is looked up in the cluster state, then, the replica level of the index is checked, then indexing on primary shard is executed, and that primary shard passes on the execution to nodes that hold replica shards. All straight forward. For bulk indexing, the consistency level setting might reflect multiple indices over multiple shards and different replica levels, and will as such executed: the sequence of single indexing actions is ordered and divided into groups of members that belong to the same shard, and sent off to the involved nodes. The nodes holding the involved shards execute the primary/replica operation in concurrency, and follow the bulk request consistency level parameter.
