How do I intersect multiple secondary index queries

由 ↘锁芯ラ 提交于 2020-01-16 00:48:10
问题 If I have a table with multiple secondary indexes, how do I generate an intersection? For example, if I have a users table with secondary indexes on "firstName" and "lastName", and want all users named 'Bob Smith': r.table('users').getAll('Bob', {index: 'firstName'}).XXXX('Smith', {index: 'lastName'}) I can use a filter, but my understanding is that would be slower: r.table('users').getAll('Bob', {index: 'firstName'}).filter({'lastName': 'Smith'}) Alternatively, can I do intersections with a

RethinkDB multiple queries in a single request

由 笑着哭i 提交于 2020-01-13 08:45:10
问题 I'm trying to execute several RQL commands in a single request to server, without much success I may add. I have tried r.union , but it only works with sequences. What I really want: [r.db(..).table(..).get(id1).delete(), r.db(..).table(..).get(id2).delete(), r.db(..).table(..).insert(...)].run_all_at_once Is there any way to do this? Thanks! 回答1: You can do r.expr( [r.db(...).table(...).get(id1).delete(), r.db(...).table(...).get(id1).delete(), r.db(...).table(...).insert(...) ] ).run(conn)

Docker集中化web界面管理平台-Shipyard部署记录

由 旧街凉风 提交于 2019-12-28 01:10:57
Docker图形页面管理工具基本常用的有三种: DOCKER UI，Shipyard，Portainer 。对比后发现， Shipyard最强大，其次是Portainer,最后是Docker ui 。之前介绍了 DOcker的web管理工具DockerUI ，下面介绍下Docker的另一个web界面管理工具Shipyard的使用。Shipyard（github）是建立在docker集群管理工具Citadel之上的可以管理容器、主机等资源的web图形化工具,包括core和extension两个版本，core即shipyard主要是把多个 Docker host上的 containers 统一管理（支持跨越多个host），extension即shipyard-extensions添加了应用路由和负载均衡、集中化日志、部署等;Shipyard是在Docker Swarm实现对容器、镜像、docker集群、仓库、节点进行管理的web系统。 DockerUI功能： 通过Web浏览器的命令行来管理的任务。 DockerUI的优点 1）可以对运行着的容器进行批量操作 2）在容器网络中-会显示容器与容器间的网络关系 3）在Volumes中显示了所有挂载目录 DockerUI一个致命的缺点：不支持多主机.试想一下，如果有N台docker主机时-我就需要一台台的用dockerui进行管理

How do I get the rank / row number for a row?

由 喜欢而已 提交于 2019-12-24 15:01:14
问题 Is there a way to get the row numbers (rank) for a filtered set and append the row number to the result? An example scenario would be that I have a table with records like: [ { points: 123, name: 'Glenn' }, { points: 948, name: 'Bob' }, { points: 22, name: 'Sarah' } ] In the above table there are hundreds of thousands of rows, and I want to be able to rank all records based on a condition like points descending and then return a subset of the rows (using a filter) with their rank value
