SQLKeyValueStore (Nuxeo ECM Projects 10.10 API)

java.lang.Object
- org.nuxeo.runtime.kv.AbstractKeyValueStoreProvider
- - org.nuxeo.ecm.core.storage.sql.kv.SQLKeyValueStore

All Implemented Interfaces:

KeyValueStore, KeyValueStoreProvider
```
public class SQLKeyValueStore
extends AbstractKeyValueStoreProvider
```
SQL implementation of a Key/Value Store Provider.
The following configuration properties are available:
- datasource: the datasource to use.
- table: the table to use. The default is the Store name.
If a namespace is specified, it is used as a table name suffix, otherwise of the store name.
This implementation uses a table with a KEY column (unique and not NULL), and for the value one of these three columns is used: LONG, STRING, BYTES. If possible LONG is used, then STRING, otherwise BYTES.
The TTL is stored as an expiration time (seconds since epoch) in its own column. Expiration is done by a thread running a cleanup DELETE query every 60 seconds.
Since:

10.10

```
    Description copied from interface: KeyValueStore
    
    Atomically adds the delta to the value associated to the key, interpreted as a long represented as a string.
    If the value does not exist (if KeyValueStore.get(java.lang.String) would return null), it is interpreted as 0.
    
    Specified by:
    
    addAndGet in interface KeyValueStore
    
    Overrides:
    
    addAndGet in class AbstractKeyValueStoreProvider
