Package io.debezium.performance.engine

Class PostgresEndToEndPerf

java.lang.Object

io.debezium.performance.engine.PostgresEndToEndPerf

Direct Known Subclasses:

PostgresEndToEndPerf_jmhType_B1

public class PostgresEndToEndPerf
extends Object

Basic end-to-end comparison between EmbeddedEngine and AsyncEmbeddedEngine. Heavily inspired by JMH benchmark EndToEndPerf for Oracle connector and reusing parts of its code, this test pre-creates specified number of records in the Postgres database and measure how long it takes to the engine to process them and store in an in-memory queue.
