AcidUtils.AcidOperationalProperties (Hive Query Language 4.0.0 API)

java.lang.Object
- org.apache.hadoop.hive.ql.io.AcidUtils.AcidOperationalProperties

Enclosing class:

AcidUtils
```
public static class AcidUtils.AcidOperationalProperties
extends Object
```
Current syntax for creating full acid transactional tables is any one of following 3 ways: create table T (a int, b int) stored as orc tblproperties('transactional'='true'). create table T (a int, b int) stored as orc tblproperties('transactional'='true', 'transactional_properties'='default'). create table T (a int, b int) stored as orc tblproperties('transactional'='true', 'transactional_properties'='split_update'). These are all identical and create a table capable of insert/update/delete/merge operations with full ACID semantics at Snapshot Isolation. These tables require ORC input/output format. To create a 1/4 acid, aka Micro Managed table: create table T (a int, b int) stored as orc tblproperties('transactional'='true', 'transactional_properties'='insert_only'). These tables only support insert operation (also with full ACID semantics at SI).

- Method Detail
  - getDefault
```
public static AcidUtils.AcidOperationalProperties getDefault()
```
    Returns an acidOperationalProperties object that represents default ACID behavior for tables that do no explicitly specify/override the default behavior.
    
    Returns:
    
    the acidOperationalProperties object.
  - getInsertOnly
```
public static AcidUtils.AcidOperationalProperties getInsertOnly()
```
    Returns an acidOperationalProperties object for tables that uses ACID framework but only supports INSERT operation and does not require ORC or bucketing
    
    Returns:
    
    the acidOperationalProperties object
  - parseString
```
public static AcidUtils.AcidOperationalProperties parseString(String propertiesStr)
```
    Returns an acidOperationalProperties object that is represented by an encoded string.
    
    Parameters:
    
    propertiesStr - an encoded string representing the acidOperationalProperties.
    
    Returns:
    
    the acidOperationalProperties object.
  - parseInt
```
public static AcidUtils.AcidOperationalProperties parseInt(int properties)
```
    Returns an acidOperationalProperties object that is represented by an encoded 32-bit integer.
    
    Parameters:
    
    properties - an encoded 32-bit representing the acidOperationalProperties.
    
    Returns:
    
    the acidOperationalProperties object.
  - setSplitUpdate
```
public AcidUtils.AcidOperationalProperties setSplitUpdate(boolean isSplitUpdate)
```
    Sets the split update property for ACID operations based on the boolean argument. When split update is turned on, an update ACID event is interpreted as a combination of delete event followed by an update event.
    
    Parameters:
    
    isSplitUpdate - a boolean property that turns on split update when true.
    
    Returns:
    
    the acidOperationalProperties object.
  - setHashBasedMerge
```
public AcidUtils.AcidOperationalProperties setHashBasedMerge(boolean isHashBasedMerge)
```
    Sets the hash-based merge property for ACID operations that combines delta files using GRACE hash join based approach, when turned on. (Currently unimplemented!)
    
    Parameters:
    
    isHashBasedMerge - a boolean property that turns on hash-based merge when true.
    
    Returns:
    
    the acidOperationalProperties object.
