clojure - 为什么使用 onyx 的棱柱模式验证失败(ExceptionInfo 值与模式不匹配)？

Question

有人能解释一下这里发生了什么吗？我已经仔细检查过dynamodb-local使用非onyxian客户端的行为和简单的操作使用 Faraday 。我尝试运行的代码是 here我记录了一个问题 here但还没有得到任何回复。

这是 REPL 的输出:

$ lein repl

使用*e的完整堆栈跟踪如下:-

Faraday 客户端 REPL(my-ns 是用于测试的本地命名空间)的输出将连接到本地运行的同一 dynamodb，如下所示:

my-ns=> (far/list-tables client-opts)
(:events)

my-ns=> (far/describe-table client-opts :events)
{:lsindexes nil, :gsindexes [{:name :event-idx, :size 0, :item-count 0, :key-schema [{:name :type, :type :hash} {:name :date, :type :range}], :projection {:projection-type "ALL", :non-key-attributes nil}, :throughput {:read 1, :write 1, :last-decrease nil, :last-increase nil, :num-decreases-today nil}}], :name :events, :throughput {:read 1, :write 1, :last-decrease #inst "1970-01-01T00:00:00.000-00:00", :last-increase #inst "1970-01-01T00:00:00.000-00:00", :num-decreases-today 0}, :prim-keys {:id {:key-type :hash, :data-type :s}, :date {:key-type :range, :data-type :n}, :type {:data-type :s}}, :size 0, :status :active, :item-count 0, :creation-date #inst "2016-03-10T22:53:33.601-00:00", :indexes nil}

我已经为 core.clj 创建了一个公共(public)要点 here对于cqrs.cljhere供审查。 我的 project.clj 看起来像 this .

有人可以帮我解决这个问题吗？
TIA

根据您提供的信息和我们的聊天，您问题的直接答案是配置中 :catalog 向量中的最后一个条目缺少键，如架构验证错误所示:

{:onyx/consumationmissing-required-key,:onyx/batch-sizemissing-required-key,:onyx/mediummissing-required-key}

有问题的条目(向量中的最后一个)是:

{:onyx/name :event/aggregate-out, :onyx/type :output}

您需要修复它，以便它包含那些丢失的键:

{:onyx/name :event/aggregate-out,
 :onyx/type :output,
 :onyx/consumption <some value here>,
 :onyx/batch-size <some value here>,
 :onyx/medium <some value here>}

但总的来说，我会重新考虑您的总体方法。您想实现什么目标？

在我看来，不值得为基于“随机”选择的旧提交的框架而奋斗，该旧提交似乎包含处于损坏状态的代码。如果您发现 cqrs-server 中的错误，您将如何支持您的应用程序？您会从该自定义提交开始自己 fork 并支持它吗？

我宁愿从您对问题的要求开始，然后使用更可靠和更好支持的库/框架来评估解决方案，以便您有更好的机会支持您的项目。
