Pilot is a tool that installs onto your Sentry and Validator servers. It can be used to control the server, as well as talk to the Commander. The Pilot will gather information from gaiad, the server, and the Cosmos Network. Then it will act on that information based on what is appropriate.

I installed ubuntu server VM on Azure there I installed couchbase community edition on now i need to access the couchbase using dotnet SDK but code gives me bucket not found or unreachable error. even i try configuring a public dns and gave it as ip during cluster creation but still its giving the same. even i added public dns to the host file like below 127.0.0.1 public dns The SDK log includes below 2 statements Attempted bootstrapping on endpoint "name.eastus.cloudapp.azure.com" has failed. (e80489ed) A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Answered 2022-Feb-11 at 17:23Thank you for providing so much detailed information! I suspect the immediate issue is that you are trying to connect using TLS, which is not supported by Couchbase Community Edition (at least not as of February 2022). Ports 11207 and 18091 are for TLS connections; as you observed in the lsof output, the server is not listening on those ports.

QUESTION
We have Beam data pipeline running on GCP dataflow written using both Python and Java. In the beginning, we had some simple and straightforward python beam jobs that works very well. So most recently we decided to transform more java beam to python beam job. When we having more complicated job, especially the job requiring windowing in the beam, we noticed that there is a significant slowness in python job than java job which end up using more cpu and memory and cost much more.
some sample python code looks like:
...ANSWER
Answered 2022-Jan-21 at 21:31Yes, this is a very normal performance factor between Python and Java. In fact, for many programs the factor can be 10x or much more.
The details of the program can radically change the relative performance. Here are some things to consider:
- Profiling the Dataflow job (official docs)
- Profiling a Dataflow pipeline (medium blog)
- Profiling Apache Beam Python pipelines (another medium blog)
- Profiling Python (general Cloud Profiler docs)
- How can I profile a Python Dataflow job? (previous StackOverflow question on profiling Python job)
If you prefer Python for its concise syntax or library ecosystem, the approach to achieve speed is to use optimized C libraries or Cython for the core processing, for example using pandas/numpy/etc. If you use Beam's new Pandas-compatible dataframe API you will automatically get this benefit.

QUESTION
I'm using the direct runner of Apache Beam Python SDK to execute a simple pipeline similar to the word count example. Since I'm processing a large file, I want to display metrics during the execution. I know how to report the metrics, but I can't find any way to access the metrics during the run.
I found the metrics() function in the PipelineResult, but it seems I only get a PipelineResult object from the Pipeline.run() function, which is a blocking call. In the Java SDK I found a MetricsSink, which can be configured on PipelineOptions, but I did not find an equivalent in the Python SDK.
How can I access live metrics during pipeline execution?
...ANSWER
Answered 2021-Aug-16 at 17:41The direct runner is generally used for testing, development, and small jobs, and Pipeline.run() was made blocking for simplicity. On other runners Pipeline.run() is asynchronous and the result can be used to monitor the pipeline progress during execution.
You could try running a local version of an OSS runner like Flink to get this behavior.
QUESTION
I am trying to create a select query with a simple where-clause using Haskell's beam. From https://haskell-beam.github.io/beam/user-guide/queries/select/#where-clause, I believed that this would work:
...ANSWER
Answered 2021-Dec-30 at 14:31On the offending line, bar :: Word32 (per the signature of selectFoosByBar).
I think _fooBar foo is a Columnar (something) Word32.
The error message says the problem is with the first arg to ==., but looking at the type of ==., I think you could change either side to get agreement.
Why is bar :: Word32? It makes intuitive sense; you're trying to filter by a word so the arg should be a word. That suggests that you probably want to do something to _fooBar foo to get a Word32 "out of" it. That might be a straightforward function, but more likely it's going to be the opposite: somehow lifting your ==. bar operation up into the "query expression" space.

Apache Beam update values based on the values from the previous row
I have grouped the values from a CSV file. Here in the grouped rows, we find a few missing values which need to be updated based on the values from the previous row. If the first column of the row is empty then we need to update it by 0.
I am able to group the records, But unable to figure out a logic to update the values, How do I achieve this?

...ANSWER
Answered 2021-Nov-11 at 15:01Beam does not provide any order guarantees, so you will have to group them as you did.
But as far as I can understand from your case, you need to group by customerId. After that, you can apply a PTransform like ParDo to sort the grouped Rows by date and fill missing values however you wish.
Example sorting by converting to Array
QUESTION
I am trying to implement apache beam for a streaming process where I want to calculate the min(), max() value of an item with every registered timestamp.
Eg:
Timestamp item_count 2021-08-03 01:00:03.22333 UTC 5 2021-08-03 01:00:03.256427 UTC 4 2021-08-03 01:00:03.256497 UTC 7 2021-08-03 01:00:03.256499 UTC 2Output :
Timestamp Min Max 2021-08-03 01:00:03.22333 UTC 5 5 2021-08-03 01:00:03.256427 UTC 4 5 2021-08-03 01:00:03.256497 UTC 4 7 2021-08-03 01:00:03.256499 UTC 2 7I am not able to figure out how do I fit my use-case to windowing, since for me the frame starts from row 1 and ends with every new I am reading. Any suggestions how should I approach this?
Thank you
...ANSWER
Answered 2021-Nov-06 at 13:11This is not going to be 100% perfect, since there's always going to be some latency and you may get elements in wrong order, but should be good enough.

Install beam
You can use beam like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
