How to select multiple random elements from a LUA table?

By -

I'm trying to figure out how to randomly select multiple entries in a table.

This is what I have currently


local letters = {"w", "x", "y", "z"}


function randomletterselect()
    local randomletters = {}
    
    for i,v in pairs(letters) do
        table.insert(randomletters,i)
    end
    local letter = letters[randomletters[math.random(#randomletters)]]
    -- set multiple selected letters to the new table?

end
randomletterselect()

this code here works for selecting ONE random element(letter) from the table. essentially, when I run this, I want it to be multiple random letters selected. for example, one time it may select x,y another time it may be x,y,z.

The closest thing I found was honestly just what I had figured out, in this post Randomly select a key from a table in Lua

Spring Elasticsearch Operations

Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate JPA @OnDelete Example

By -
@OnDelete The @OnDelete annotation is used to specify the delete strategy employed by the currently annotated collection, array or joined subclasses. This annotation is used by the automated schema generation tool to generated the appropriate FOREIGN KEY DDL cascade directive. The two possible strategies are defined by the OnDeleteAction enumeration: CASCADE Use the database FOREIGN KEY cascade capabilities. NO_ACTION Take no action. OnDelete Strategy to use on collections, arrays and on joined subclasses delete. OnDelete of secondary tables currently not supported. @OnDelete cascade While the previous cascade types propagate entity state transitions, the @OnDelete cascade is a DDL-level FK feature which allows you to remove a child record whenever the parent row is deleted. So, when annotating the @ManyToOne association with @OnDelete( action = OnDeleteAction.CASCADE ), the automatic schema generator will apply the ON DELETE CASCADE SQL directive to the Foreign Key...
