Yep.  Working on a blog post to highlight both parts...writer and reader.  

U is not really possible. For D, both DELETE and/or DROP statements are 
allowed through InfluxQL.

@timhallinflux Based on my extremely limited knowledge of what InfluxDB can 
do, I don't know if even the U or D from CRUD are really applicable to InfluxDB 
for example. What I'd like to see is some input that would help us mold this 
bundle to maxing out the reasonable use cases where NiFi and InfluxDB can 
sensibly work together if that makes sense.

@timhallinflux if you don't mind, please take some time to think about 
additional NiFi-related use cases and either post them to the dev mailing list 
or add them as Jira tickets.

@MikeThomsen - 

I've updated the code (added expression language scope and updated tests) 
based your review comments.  The integration tests are passing.  

Please let me know if there is any other comment.

Thanks

Mans

Github user MikeThomsen commented on the issue:

https://github.com/apache/nifi/pull/2562
  
@mans2singh I went to merge your changes this morning and found that you 
have some integration tests that are broken now with the changes made to EL 
support in the `PropertyDescriptor.Builder` class. It seems your breakage is 
limited mainly here:

```
protected String makeProvenanceUrl(final ProcessContext context, String 
database, FlowFile flowFile) {
return new StringBuilder("influxdb://")

.append(context.getProperty(INFLUX_DB_URL).evaluateAttributeExpressions(flowFile).getValue()).append("/")
.append(database).toString();
}
```

You marked that property as `VARIABLE_REGISTRY` and it is failing because 
you're applying it flowfiles. The existing calls to 
`expressionLanguageSupported(boolean)` in the abstract class also need to be 
fixed.

So just do a rebase against the latest master and take care of those. If 
there are no regressions after your commit (ie your flows and tests run) IMO 
we're ready to merge.

Thanks @MikeThomsen for your reveiw/advice.  Also thanks @timhallinflux for 
the pointers on influxdb sandbox.

Please let me know if there is other feedback.

@timhallinflux @mans2singh already provided a decent enough Docker Compose 
test for it. So unless @joewitt or someone else sees something that I missed 
that's a show stopper, I think we're good to go on merging this to master when 
1.6 is released into the wild.

@joewitt and @MikeThomsen -- you can also just quickly spin up the TICK 
stack via the sandbox.
Have a look here... https://github.com/influxdata/sandbox

If @joewitt is no longer technical enough to run this, I'll be more than 
happy to do a screen share and help him out! :-)

Thank you @mans2singh for contributing this!

Let's use `assertNull` here to make it a bit more readable.

Redundant because you can use `runner.enqueue("")` for cases like this 
where you're not examining the original input flowfile contents.

I think it would be a good addition to have: 
`assertNotNull(queryResult.getResults())` before this.

What I have done in a few processors is something like this:
```
String getQuery (final ProcessSession session, final ProcessContext 
context, Charset charset, FlowFile incomingFlowFile) throws IOException {
if (context.getProperty(QUERY).isSet()) {
return 
context.getProperty(QUERY).evaluateAttributeExpressions(incomingFlowFile).getValue();
} else {
//Load from file
   if (StringUtil.isBlank(query)) {
   throw new IOException("Query was missing from the flowfile 
body");
   } else {
   return query;
   }
}
}
```

@MikeThomsen - 

I've updated the code based on your comments.  Let me know if you have any 
more recommendations.

I should also mention that there are Groovy JUnits in the codebase already, 
so if you want to redo these tests w/ Groovy following other examples that is

If you can parse this with Gson and evaluate it that way, the test will be 
less likely to be brittle as InfluxDB evolves.

Verified that both flows work against the Docker Compose configuration. 
Looking very good so far.

https://github.com/apache/nifi/pull/2562
  
@MikeThomsen - I've updated the code based on your comments (added check 
for query result null, changed scheduled query property name).  One note, if we 
use the influxdb-compose.xml file for integration testing, we will need to 
change the name of the db (from test to something else) which the curl loader 
uses, since integration test use their own data.

Please let me know your thoughts/recommendations.

Thanks.

I call the cleanup in setup as a precaution so that if there is any 
conflicting/previously existing data in the test database, it is removed and 
does not fail the integration test which depend on number of rows inserted.  If 
you think it is unnecessary, I can remove it.

Changed the attribute to INFLUX_DB_QUERY.  The description mentions that 
flow files and timed query both are allowed.

What I meant was that the cleanup functionality shouldn't be called in the 
init, but should be called from the `@After` annotated method.

I think calling it a "scheduled query" might be a bit confusing. In other 
places like `GetMongo` it's just `Query` and documents that this field will be 
used if it's filled in, otherwise it'll try to extract the query from the body. 
Might want to also note that you can use this w/ an incoming connection and use 
the flowfile to power the EL.

Github user mans2singh commented on the issue:

https://github.com/apache/nifi/pull/2562
  
@joewitt @MikeThomsen - 

I've updated the code based on your comments.  

I've also added a docker gist 
[influxdb-compose.xml](https://gist.github.com/mans2singh/5ee90620314d4bcf26d6c65de2540c77#file-influxdb-compose-xml)
 based on docker compose xml mentioned by @MikeThomsen .  This docker compose 
starts a local influxdb and runs curl commands to create a `test` database and 
populate it with a metric every 5 seconds.  To launch it we need to run 
`docker-compose -f  up` on the local machine and then we can run the 
integration tests for the query processor or run Nifi locally with processor 
configured for scheduled query.

I am also including two templates ([flow file 
driven](https://gist.github.com/mans2singh/5ee90620314d4bcf26d6c65de2540c77#file-nifi-influxdb-flow-file-driven-template)
 and [timer 
driven](https://gist.github.com/mans2singh/5ee90620314d4bcf26d6c65de2540c77#file-nifi-influxdb-scheduled-query-template))
 to assist in testing the InfluxDB query processor.

Please let me know if your comments/recommendations.

Thanks again.

I've refactored the code and call it both from `Before` and `After` to make 
sure that the test setup and tear down is clean.

I've changed the order and call init database before initializing runner.  
Let me know if that is ok.

Making input optional could be quite useful. See ExecuteSQL and GetMongo 
for an example of how to support timer and event driving.

This can be merged into the other init function. It should at least come 
after the database init code so that you don't spend any time spinning up 
testing infra on the NiFi side if the database isn't working.

@mans2singh thanks for contributing.  What we need most right now is help 
reviewing outstanding PRs.  This involves reviewing code and validating as 
possible whether things are actually functioning.  For things like this it can 
be tougher because it means someone needs an environment with influx 
running/etc.. and familiarity on how to do so.  What can you do?  You can 
provide detailed instructions a reviewer could follow to verify functionality.  
Perhaps a pointer to a docker container which eases the process.  And help with 
reviews on other items, for example.  Not saying someone wont look at this 
until then - they certainly might.  Just giving you tips to help ease the 
process.
