@wuchong @loserwang1024 Is there anyone work on this? if not, I'd like to
add tests for this issue.
I plan to add a test in `TabletServiceITCase`, and follow this steps
1. create table and add data
2. add array column with `DATA4_SCHEMA` and produce data
``` java
public static final Schema DATA4_SCHEMA =
Schema.newBuilder()
.column("a", DataTypes.INT())
.withComment("a is first column")
.column("b", DataTypes.STRING())
.withComment("b is second column")
.column("c", DataTypes.ARRAY(DataTypes.INT()))
.withComment("c is adding array column")
.primaryKey("a")
.build();
```
3. check if it can fetch only third field success
4. add row column with `DATA5_SCHEMA` and produce data
``` java
public static final Schema DATA5_SCHEMA =
Schema.newBuilder()
.column("a", DataTypes.INT())
.withComment("a is first column")
.column("b", DataTypes.STRING())
.withComment("b is second column")
.column("c", DataTypes.ARRAY(DataTypes.INT()))
.withComment("c is adding array column")
.column(
"d",
DataTypes.ROW(
DataTypes.FIELD("r1", DataTypes.INT()),
DataTypes.FIELD("r2", DataTypes.STRING())))
.withComment("d is adding nested row column")
.primaryKey("a")
.build();
```
6. check if it can fetch only fourth field success
