Retrieve values from a SdkPublisher

I just started working with dynamodb, and I couldnt figure out how to retrieve values from SdkPublisher.
My code is using dynamoDBAsyncClient, and I want migrate to dynamodbEnhancedAsyncClient.
I tried to use this example on https://github.com/aws/aws-sdk-java-v2/blob/master/services-custom/dynamodb-enhanced/README.md#non-blocking-asynchronous-operations
List<String> tables = Flowable.fromPublisher(publisher)
.flatMapIterable(ListTablesResponse::tableNames)
.toList()
.blockingGet();
But this example retrieves table names and when I adapted for my situation it blocks on "blockingGet()".

Fusion Charts FusionTime making a time-series chart from mySQL

I am a beginner at all things coding but need some help with Fusion Charts if anyone can help.
I have followed along with tutorials already for Fusion Charts linking it to MySQL database and displaying a chart with no issues.
However, I would like to display a time-series chart, which uses FusionTime. This requires the data to be in a Datatable. " FusionTime accepts data in rows and columns as a Datatable".
I cannot find any examples online for taking SQL data and converting into a datatable with data and schema which it seems to require. This is different from the way fusioncharts works.
https://www.fusioncharts.com/dev/fusiontime/getting-started/create-your-first-chart-in-fusiontime
My SQL database contains many tables and many columns within it, so will need to select the appropriate column to display.
I would appreciate any advice anyone can provide. The main problem is I don't know how to get the SQL database into a data and schema file to display with fusiontime. This is to display on a webpage hosted locally.
Many thanks for any time you can provide to help with this

ft needs a json, you must write a file from php type json
like this
.....
$result = json_encode($dataIngGast, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE |JSON_NUMERIC_CHECK | JSON_PRETTY_PRINT);
//echo $result;
$arquivo = "column-line-combination-data-gasto-ingreso-finanzas.json";
$fp = fopen($arquivo, "a+");
fwrite($fp, $result);
fclose($fp);

Adding new columns to Schema of BigQuery Table in Java

I am looking for ways to update Schema of an existing table in BigQuery. I could see doing the same in python here which is an API Request. I wanted to see this in Java and going through documentation and source code I could find
TableDefinition tableDefinition = StandardTableDefinition.of(schema);
table.toBuilder().setDefinition(definition)
But it rewrites the whole schema. Other possible of ways of updating schema can be found here
Can someone guide me regarding adding new columns to existing table in BigQuery using Java ?

Have a look in this github issue. You need to specify the entire schema again -including your new cols.

In AEM query builder order by based on someproperty=somevalue

I m trying to sort the AEM query builder search results based on particular value of particular property. as we have in any database like MySQL we can sort based on column's value as well (for exp. ORDER BY FIELD('columnName','anyColumnName'). can we have something like this in AEM.
Suppose we have 5 Assets under path /content/dam/Assets.
Asset Name------------dc:title
1.jpg------------------Apple
2.jpg------------------Cat
3.jpg------------------Cat
4.jpg------------------Ball
5.jpg------------------Drag
I need assets on top of the results where dc:title = cat and also need other results also in sorting asc. expected result as given below
2.jpg------------------Cat
3.jpg------------------Cat
1.jpg------------------Apple
4.jpg------------------Ball
5.jpg------------------Drag
Note:- Using version AEM 6.2

You can use the orderby predicate with a value of #jcr:content/metadata/dc:title to sort by dc:title with the QueryBuilder. /libs/cq/search/content/querydebug.html is an interface to test queries on your instance. ACS Commons has a good breakdown of all out of the box predicates
If you want to pull Cats to the top of the results with a single query, you could write a custom predicate. The sample code from ACS Commons shows an example. Adobe has documentation as well.

Lucene Autocomplete in JSON data

I am trying to build a search engine using Neo4j as backend & Java web application as frontend. Using Neo4j Java API, the data extracted is in JSON format. Any idea how to query the JSON data using Lucene for providing autocomplete suggestions to the user ???

Suggest lucene
Check this thread I used this to create my autocomplete and richfaces for display this

For autocomplete there's a very helpful new feature in 2.3:
MATCH (n:Person)
WHERE n.name starts with 'Jo'
RETURN n
returns person nodes like 'John' and 'Joanne' based on a index search.
Of course the index has be created using
CREATE INDEX ON :Person(name)
