Hi Adam,
a)
Searching with/in text in RDBMS like Mysql with like query e.t.c is really bad for performance.
I'm trying to find a way to use something like Apache Lucene with EclipseLink . I checked Hibernate Search but this is only for Hibernate. Any ideas?
Also, In my case i cannot use an extrernal server like Solr. I 'm looking for some library.
b) About jee testing. I checked up the TestContainers (https://www.testcontainers.org) to integrate real databases instances and not memory databases (like derby) to our junit code as we used to . What is opinion about this approach?
c) We have increased max connections in Wildfly datasource but if this number is reached then wildfly gives no other connection to other requests so it will be frozen..... Any proposal for handling this situation? (besides increasing all the time the max connections).
Or we just keep increasing datasource and database max connections....we can check percona article about 100.000 connections in a single mysql server instance https://www.percona.com/blog/2019/02/25/mysql-challenge-100k-connections/!!!!!
Thanks!!!!
