Add integration JDBC tests for cursor/fetch_size feature

[Yury-Fridlyand]

• Add integration JDBC tests for cursor/fetch_size feature.

Signed-off-by: Yury-Fridlyand yury.fridlyand@improving.com

See team review and discussion on Bit-Quill#208

Description

Add new IT suite which uses JDBC to issue queries with and without fetch_size set.
fetch_size parameter invokes pagination feature (cursor) which is currently supported by legacy engine only.

New :integ-test tasks:

integJdbcTest

Run ITs from **/jdbc/*.java. Existing tests in CursorIT create and use DB connection using JDBC driver from maven artifact.

Optional parameters:

• -Dtest.debug
  Enabled test debug.
• --tests '<test_filter>
  Filter test using wildcard, could be specified multiple times.
• -DjdbcDriverVersion=<version>
  Maven artifact version for JDBC driver to use; optional, defaulted to 1.2.0.0.
• -DjdbcFile=<file>
  Relative or absolute path to JDBC driver compiled binary (*.jar); if given, test platform uses it.
• -DjdbcRepo=<repo_path>
  Relative or absolute path to JDBC driver Maven repo to get the driver from. Note: it is highly recommended to have non-default version of the driver in this repo to avoid conflicts.

Test cluster log located in integ-test/build/testclusters/integJdbcTest-0/logs/integJdbcTest.log
Test report saved in integ-test/build/reports/tests/integJdbcTest

Examples:

./gradlew :integ-test:integJdbcTest

# go to SQL JDBC repo
cd sql-jdbc
# build the driver
./gradlew build
# go to SQL plugin repo
cd ../sql
# run tests
./gradlew :integ-test:integJdbcTest '-DjdbcFile=../sql-jdbc/build/libs/opensearch-sql-jdbc-2.0.0.0.jar'

# go to SQL JDBC repo
cd sql-jdbc
# build the driver and publish to local repo
./gradlew publishShadowPublicationToLocalRepoRepository
# go to SQL plugin repo
cd ../sql
# run tests
./gradlew :integ-test:integJdbcTest '-DjdbcRepo=../sql-jdbc/build/repository/' -DjdbcDriverVersion=2.0.0.0

# run tests with non-default (e.g. non-latest) released JDBC version
./gradlew :integ-test:integJdbcTest -DjdbcDriverVersion=1.0.0.0

Output sample:

> Task :integ-test:integJdbcTest
org.opensearch.sql.jdbc.CursorIT.select_count_all_no_cursor(): SUCCESS 19.634s

CursorIT > select count all no cursor PASSED
org.opensearch.sql.jdbc.CursorIT.select_all_big_table_small_cursor(): SUCCESS 8.738s

CursorIT > select all big table small cursor PASSED
org.opensearch.sql.jdbc.CursorIT.select_all_small_table_small_cursor(): SUCCESS 0.238s

CursorIT > select all small table small cursor PASSED
org.opensearch.sql.jdbc.CursorIT.select_all_no_cursor(): SUCCESS 4.163s

CursorIT > select all no cursor PASSED
org.opensearch.sql.jdbc.CursorIT.select_all_small_table_big_cursor(): SUCCESS 0.132s

CursorIT > select all small table big cursor PASSED
org.opensearch.sql.jdbc.CursorIT.select_all_big_table_big_cursor(): SUCCESS 3.398s

CursorIT > select all big table big cursor PASSED
org.opensearch.sql.jdbc.CursorIT.dev_select_all_small_table_small_cursor(): SUCCESS 20.008s

CursorIT > dev_select_all_small_table_small_cursor() PASSED

Notes

Test filter in gradle

requires
https://github.com/Bit-Quill/opensearch-project-sql/blob/24de6ff9eae35a824a664a865ad349788b744288/integ-test/build.gradle#L177
and doesn't work with JUnit 4. All IT framework uses Junit 4.
So, init() method of test classed isn't being called from superclasses automatically.
@BeforeAll/@BeforeClass require a static method, so I can't call initClient() there. I have to move initClient() to @BeforeEach with initialized flag.

New gradle tasks are not included into CI workflow.

Being able to set JDBC driver version is sufficient to run these tests against a development version of the driver.

I'd keep jdbc integration test suite and remove jdbcDev, cloneJdbcDriverRepo, and integDevJdbcTest .

[MaxKsyunz]

Looks like the cloneJdbcDriverRepo task is breaking both SQL Java CI and CodeQL-Scan.

Rebased + added a fix for ITs. Shouldn't affect BWC.
