Spark ETL pipelines. Hudi
datasources work (e.g: `spark.read.parquet`). Both snapshot querying and
incremental querying are supported here. Typically spark jobs require adding
`--jars <path to jar>/hudi-spark-bundle_2.11-<hudi version>.jar` to classpath
of drivers
and executors. Alternatively, hudi-spark-bundle can also fetched via the
`--packages` options (e.g: `--packages
org.apache.hudi:hudi-spark-bundle_2.11:0.5.3`).
+### Snapshot query {#spark-snap-query}
+This method can be used to retrieve the data table at the present point in
time.
+
+```scala
+val hudiIncQueryDF = spark
+ .read()
+ .format("org.apache.hudi")
+ .option(DataSourceReadOptions.QUERY_TYPE_OPT_KEY(),
DataSourceReadOptions.QUERY_TYPE_SNAPSHOT_OPT_VAL())
+ .load(tablePath + "/*") //Include "/*" at the end of the path if the
table is partitioned
