Apache Calcite is a dynamic data management framework. It contains many of the pieces that comprise a typical database management system but omits the storage primitives. It provides an industry standard SQL parser and validator, a customisable optimizer with pluggable rules and cost functions, logical and physical algebraic operators, various transformation algorithms from SQL to algebra (and the opposite), and many adapters for executing SQL queries over Cassandra, Druid, Elasticsearch, MongoDB, Kafka, and others, with minimal configuration.

Single layer visible (toggle) in LayerList widget (ArcGIS JavaScript 4.X)

Asked 2021-May-24 at 08:37

Is it possible to display only one layer on the map using ArcGIS JavaScript 4.X?

I am looking for the exact same functionality from (Single layer visible in LayerList widget (ArcGIS JavaScript)) in 4.x, I am able to make it work a little bit but it had some issues

need to click twice on the eye icon when toggling, ex: layer 1 click and then click on layer 2 it was just unchecking the layer 1, I am looking for a radio button functionality
current toggle applies for both layer and sublayers, I am looking for toggle only for the top layers, sublayers should just work as a checkbox.

Could you please check my fiddle below?

ANSWER

Answered 2021-Apr-11 at 21:12

I believe the issue is you need to wrap your custom measure in an aggregate (AVG, SUM, etc) given the chart is creating a group-by query. For the scatterplot you can also visualize ungrouped data (by not adding anything as a dimension), in which case you would not need the aggregate wrapper.

Given the root cause error message:

java.lang.RuntimeException: org.apache.calcite.tools.ValidationException: org.apache.calcite.runtime.CalciteContextException: From line 1, column 8 to line 1, column 58: Cannot apply 'DS_GET_QUANTILE' to arguments of type 'DS_GET_QUANTILE(, )'. Supported form(s): 'DS_GET_QUANTILE(, )'

This is a problem with type inference for the parameter. Try explicitly casting the parameter to a numeric type, e.g. cast(? as double).

ANSWER

Answered 2021-Feb-16 at 10:47

In order to do using the table API to perform event-time windowing on your datastream, you'll need to first assign timestamps and watermarks. You should do this before calling fromDataStream.

With Kafka, it's generally best to call assignTimestampsAndWatermarks directly on the FlinkKafkaConsumer. See the watermark docs, kafka connector docs, and Flink SQL docs for more info.

QUESTION

No Map Shows If I Modify the Basemap on Esri-React-Boot

Asked 2021-Feb-02 at 19:32

I am pretty stuck and do not know what I am doing wrong. I am currently just trying to modify this library from Esri (https://github.com/Esri/esri-react-boot).

It uses OAuth, but you can view the map without having to sign in. However, if I want to modify the basemap config to show arcgis-topographic like the tutorial shows here (https://developers.arcgis.com/javascript/latest/display-a-map/), I do not get any render of the map.

The tutorial uses an API Key, but when using OAuth, you shouldn't need to do anything like that.

Below are the only 2 files I have modified, everything else is the same as in the repo.

Use TableProvider to generate a table and run an SQL query in Apache Beam

Asked 2020-Dec-19 at 18:05

I want to generate an unbounded collection of rows and run an SQL query on it using the Apache Beam Calcite SQL dialect and the Apache Flink runner. Based on the source code and documentation of Apache Beam, one can do something like this using a table provider: GenerateSequenceTableProvider. But I don't understand how to use it outside of the Beam SQL CLI. I'd like to use it in my regular Java code.

I was trying to do something like this:

If you can't get TableProviders to work, you could read this as an ordinary PCollection and then apply a SqlTransform to the result.
