> Separate Fluo query result exporters, Rya PCJ intermingled kafka triggers
> -------------------------------------------------------------------------
>
> Key: RYA-246
> URL: https://issues.apache.org/jira/browse/RYA-246
> Project: Rya
> Issue Type: Improvement
> Components: dao
> Environment: Fluo, Kafka, PCJ, Accumulo
> Reporter: David W. Lotts
> Assignee: Caleb Meier
> Fix For: 3.2.11
>
>
> Currently the Fluo query observer framework (FQF) has a great plugin-in-ish
> way of doing exports. (See field: {{exporters}} in class:
> {{org.apache.rya.indexing.pcj.fluo.app.observers.QueryResultObserver}} )
> Exports are query results and the action taken when they occur. Currently
> there are two. Despite this awesome framework, there are three
> interminglings that can become issues in a production system. Feel free to
> make sub tasks for each of these three tasks:
> 1. Create PCJ independently of alerts/triggers
> At query register time (with FQF), optionally create PCJ's and optionally
> create alerts (with Alerting) preferably atomically, so if it fails in the
> middle it does not leave dangling references and garbage -- currently there
> is one method that does everything: CreatePCJ.withRyaInteraction()
> 2. Enable exporters per query -- currently all queries will be exported on
> all globally enabled exporters. When the query is registered (with FQF)
> specify the exporters that should be used.
> 3. Separate export observer queues per exporter -- Currently retrying a
> failed export observer will re-export all export types, even if some already
> succeeded, causing duplicate triggers.
> Also there is a need to refine the terms for java identifiers (for example:
> fields, classes) and documentation. Please document here a decision about
> what we name different things. The term PCJ are the index tables used by Rya
> to optimize it's queries. But sometimes it is used to describe the whole
> Fluo framework. Please define a unique term for the following. The starred
> term will be used here, but feel free to rename them:
> - Rya query optimization PCJ (ex: the Blabla exporter) PCJ*
> - Kafka trigger alert notifier (ex: the Foofoo exporter) Alerting*
> - Fluo query observer framework (ex: results from the Barbar) FQF*
> Unique identifers:
> - FQF uses QueryID
> - Alerting uses TopicID
> - PCJ uses PcjId
> Note that currently TopicID is assigned the same as QueryID, but that badly
> presupposes queryID's cannot be grouped onto one Topic.
