+### Useful Maven commands for developers.
+Listing out some of the maven commands that could be useful for developers.
+
+- Compile/build entire project
+
+```shell
+mvn clean package -DskipTests
+```
+Default profile is spark2 and scala2.11
+
+- For continuous development, you may want to build only the modules of
interest. for eg, if you have been working with
+deltastreamer, you can build using this command instead of entire project.
Majority of time goes into building all different bundles we have
+like flink bundle, presto bundle, trino bundle etc. But if you are developing
something confined to hudi-utilties, you can achieve faster
+build times.
+
+```shell
+mvn package -DskipTests -pl packaging/hudi-utilities-bundle/ -am
+```
+
+To enable multi-threaded building, you can add -T.
+```shell
+mvn -T 2C package -DskipTests -pl packaging/hudi-utilities-bundle/ -am
+```
+This command will use 2 parallel threads to build.
+
+You can also confine the build to just one module if need be.
+```shell
+mvn -T 2C package -DskipTests -pl hudi-spark-datasource/hudi-spark -am
+```
+Note: "-am" will build all dependent modules as well.
+In local laptop, entire project build can take somewhere close to 7 to 10
mins. While buildig just hudi-spark-datasource/hudi-spark
+with multi-threaded, could get your compilation in 1.5 to 2 mins.
+
+If you wish to run any single test class in java.
+```shell
+mvn test -Punit-tests -pl hudi-spark-datasource/hudi-spark/ -am -B
-DfailIfNoTests=false -Dtest=TestCleaner
+```
+
+If you wish to run a single test method in java.
+```shell
+mvn test -Punit-tests -pl hudi-spark-datasource/hudi-spark/ -am -B
-DfailIfNoTests=false -Dtest=TestCleaner#testKeepLatestCommitsMOR
+```
+
+To filter particular scala test:
+```shell
+mvn -Dsuites="org.apache.spark.sql.hudi.TestSpark3DDL @Test Chinese table "
-Dtest=abc -DfailIfNoTests=false test -pl packaging/hudi-spark-bundle -am
+```
+-Dtest=abc will assist in skipping all java tests.
+-Dsuites="org.apache.spark.sql.hudi.TestSpark3DDL @Test Chinese table "
filters for a single scala test.
