  - DISABLE_STREAMING
```
static final java.lang.String DISABLE_STREAMING

This will make the performance slower and require more memory for large query results but with more predictable results in case a server happens to go down while iterating over a ResultSet. When this is not set then an SQLException with state SQLState.GFXD_NODE_SHUTDOWN will be thrown in case a node happens to go down in the middle of ResultSet iteration and application has to retry the query. With this property set, GemFireXD will always wait for at least one result from all the nodes and disable chunking of results from nodes, so will always transparently failover in such a scenario.

    See Also:
    
    Constant Field Values
  - DISABLE_TX_BATCHING
```
static final java.lang.String DISABLE_TX_BATCHING
```
    A connection level property to disable all batching in transactions, flushing ops immediately to detect conflicts immediately. Note that this can have a significant performance impact so turn this on only if it is really required by application for some reason.

```
static final java.lang.String TX_SYNC_COMMITS
