Contains the configuration necessary to connect to a database.
Attributes
- allocator
the netty buffer allocator to be used
- charset
charset for the connection, defaults to UTF-8, make sure you know what you are doing if you change this
- connectTimeout
the timeout for connecting to servers
- database
database name, defaults to no database
- host
database host, defaults to "localhost"
- maximumMessageSize
the maximum size a message from the server could possibly have, this limits possible OOM or eternal loop attacks the client could have, defaults to 16 MB. You can set this to any value you would like but again, make sure you know what you are doing if you do change it.
- password
password, defaults to no password
- port
database port, defaults to 5432
- queryTimeout
the optional query timeout

ssl configuration
- testTimeout
the timeout for connection tests performed by pools

- trait Serializabletrait Producttrait Equalsclass Objecttrait Matchableclass Any
Base interface for all objects that behave like a connection. This trait will
usually be implemented by the objects that connect to a database, either over
the filesystem or sockets. [[Connection]]
are not supposed to be
thread-safe and clients should assume implementations are not thread safe
and shouldn't try to perform more than one statement (either common or
prepared) at the same time. They should wait for the previous statement to be
executed to then be able to pick the next one.

You can, for instance, compose on top of the futures returned by this class to execute many statements at the same time:
val handler: Connection = ...
val result: Future[QueryResult] = handler.connect
.map(parameters => handler)
.flatMap(connection => connection.sendQuery("BEGIN TRANSACTION ISOLATION LEVEL REPEATABLE READ"))
.flatMap(query => handler.sendQuery("SELECT 0"))
.flatMap(query => handler.sendQuery("COMMIT").map(value => query))
val queryResult: QueryResult = Await.result(result, Duration(5, SECONDS))

This is the result of the execution of a statement, contains basic information as the number or rows affected by the statement and the rows returned if there were any.

- class Objecttrait Matchableclass Any
Represents the collection of rows that is returned from a statement inside a
[[QueryResult]]
. It's basically a collection of Array[Any]. Mutating
fields in this array will not affect the database in any way
