Another test:
```scala
import org.apache.hive.service.rpc.thrift.TProtocolVersion
import org.apache.spark.sql.execution.HiveResult
val df = spark.sql("select id, cast(id as string), cast(id as timestamp),
cast(id as decimal(18, 0)) from range(20000000)")
val dataTypes = df.schema.fields.map(_.dataType)
val rows = df.collect().toList
val start1 = System.currentTimeMillis()
RowSetUtils.toTRowSet(1, rows, dataTypes,
TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V11,
HiveResult.getTimeFormatters)
val start2 = System.currentTimeMillis()
RowSetUtils.toTRowSet(1, rows, dataTypes,
TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V5,
HiveResult.getTimeFormatters)
val start3 = System.currentTimeMillis()
println(s"toColumnBasedSet time: ${start2 - start1}, toRowBasedSet time:
${start3 - start2}")
```
Result:
```
toColumnBasedSet time: 40678, toRowBasedSet time: 90844
```
