I spent some time on searching info on how I can check if an index exists, but failed. If it's possible with the current library state, could you please show me an example? If not, can we add it?
if (failedShard.relocatingNodeId() == null) { if (failedShard.primary()) { // promote active replica to primary if active replica exists (only the case for shadow replicas) unassignPrimaryAndPromoteActiveReplicaIfExists(failedShard, unassignedInfo, routingChangesObserver); } else { // initializ...

_seq_no:文档编号,每修改一次文档,字段就会加 1,替代老的 version。注意 seq_no 递增属于整个 index,而不是单个文档 _primary_term:文档所在主分区,这个可以跟 seq_no 搭配实现乐观锁并发控制,以防止旧版本的文档覆盖较新的文档 field 文档由多个 JSON 字段组成,字段跟 MySQL 中表的字段类似,常用字段类型有: ...
