This commit reduces the JDBC integration tests to only single (latest) version per RDBMS vendor, due to a growing number of integration tests. Additionally, the configuration of most containers is simplified due to improved defaults within the Testcontainers library.
At present, the SQL statement used to insert a session attribute record contains a nested select statement that verifies the existence of parent record in the session table. Such approach can be susceptible to deadlocks on certain RDMBSs.
This commit optimizes the SQL statement used to insert session attribute so that it doesn't perform a nested select statement.
Closes: #1550
This commit provides JdbcIndexedSessionRepository customizers for the following SQL dialects:
- PostgreSQL
- MySQL (also used by MariaDB)
- SQL Server
- IBM DB2
- Oracle
These customizers are intended to address the concurrency issues occurring on insert of new session attribute by applying SQL dialect specific SQL upsert/merge statement instead of a generic insert.
