Eventing engine based on Couchbase and Google V8

Couchbase Eventing:

==================

Effort to embed application server layer within Couchbase

Next set of items to finish:

===========================

  • Application reload when deployment.json is updated

  • Support for Timer Callbacks, sample example:

function OnUpdate(doc, meta) {
  if (meta.id.Startswith(“pymc”)) {
    RegisterCallback(CallbackFunc1, meta.id);
  } else if (meta.id.Startswith(“defg”)) {
    RegisterCallback(CallbackFunc2, meta.id);
  } else {
    RegisterCallback(CallbackFunc3, meta.id);
  }
}

function CallbackFunc1(doc, meta) {
}
function CallbackFunc2(doc, meta) {
}
function CallbackFunc3(doc, meta) {
}

  • Make sure bad javascript doesn’t crash the eventing process

  • Add TryCatch in more places within v8 binding code to trace failures, along with some assert calls.

  • Store cas value of mutations in-memory on each eventing node, in order to make callbacks idempotent

  • Support for multiple bucket/queue/n1ql/view definitions in deployment.cfg

  • Handle error messages gracefully:

    • From SendUpdate/SendDelete methods
