> Key: TINKERPOP-1801
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1801
> Project: TinkerPop

>  Components: hadoop
>Affects Versions: 3.3.0, 3.2.6
>Reporter: Artem Aliev
>
> Graph ProfileStep calculates time of next()/hasNext() calls, expecting 
> recursion.
> But Message passing/RDD joins is used by GraphComputer.
> So next() does not recursively call next steps, but message is generated. And 
> most of the time is taken by message passing (RDD join). 
> Thus on graph computer the time between ProfileStep should be measured, not 
> inside it.
> The other approach is to get Spark statistics with SparkListener and add 
> spark stages timings into profiler metrics. that will work only for spark but 
> will give better representation of step costs.
> The simple fix is measuring time between OLAP iterations and add it to the 
> profiler step.
> This will not take into account computer setup time, but will be precise 
> enough for long running queries.

Sqlg's description

[pieter gmail]

Hi,

Can I request Sqlg's description on the homepage 
 to be changed.
Sqlg now supports more back-ends and changes are that it will support 
non RDBMS but SQL databases in the future.


Can we change it to

"OLTP implementation on SQL databases."

Thanks
Pieter

[jira] [Created] (TINKERPOP-1806) Consistently use Gremlin.Net instead of Gremlin-DotNet

 Summary: Consistently use Gremlin.Net instead of Gremlin-DotNet
 Key: TINKERPOP-1806
 URL: https://issues.apache.org/jira/browse/TINKERPOP-1806
 Project: TinkerPop
  Issue Type: Task
  Components: documentation, dotnet
Affects Versions: 3.2.6, 3.3.0
Reporter: Florian Hockmann
Priority: Trivial


We agreed in TINKERPOP-1552 to name the .NET GLV and driver Gremlin.Net, but I 
used Gremlin-DotNet instead in the initial pull request. The documentation 
still uses mainly Gremlin-DotNet which could be a bit confusing to new users. 
So we should simply replace _Gremlin-DotNet_ everywhere by _Gremlin.Net_.

[jira] [Created] (TINKERPOP-1805) Document Gremlin.Net driver

[Florian Hockmann (JIRA)]

 Summary: Document Gremlin.Net driver
 Key: TINKERPOP-1805
 URL: https://issues.apache.org/jira/browse/TINKERPOP-1805
 Project: TinkerPop
  Issue Type: Task
  Components: documentation, dotnet
Affects Versions: 3.2.6, 3.3.0
Reporter: Florian Hockmann
Priority: Minor


The reference documentation contains sections for Gremlin Server about 
_Connecting via Java_ and _Connecting via Python_ that describe how to use the 
respective drivers for those languages. A similar section should be added for 
Gremlin.Net that shows how scripts can be sent to the server and which config 
options are available.
