| <div class="block">A AsyncKuduSession belongs to a specific AsyncKuduClient, and represents a context in |
| which all read/write data access should take place. Within a session, |
| multiple operations may be accumulated and batched together for better |
| efficiency. Settings like timeouts, priorities, and trace IDs are also set |
| per session.<p> |
| |
| AsyncKuduSession is separate from KuduTable because a given batch or transaction |
| may span multiple tables. This is particularly important in the future when |
| we add ACID support, but even in the context of batching, we may be able to |
| coalesce writes to different tables hosted on the same server into the same |
| RPC.<p> |
| |
| AsyncKuduSession is separate from AsyncKuduClient because, in a multi-threaded |
| application, different threads may need to concurrently execute |
| transactions. Similar to a JDBC "session", transaction boundaries will be |
| delineated on a per-session basis -- in between a "BeginTransaction" and |
| "Commit" call on a given session, all operations will be part of the same |
| transaction. Meanwhile another concurrent Session object can safely run |
| non-transactional work or other transactions without interfering.<p> |
| |
| Therefore, this class is <b>not</b> thread-safe.<p> |
| |
| Additionally, there is a guarantee that writes from different sessions do not |
| get batched together into the same RPCs -- this means that latency-sensitive |
| clients can run through the same AsyncKuduClient object as throughput-oriented |
| clients, perhaps by setting the latency-sensitive session's timeouts low and |
| priorities high. Without the separation of batches, a latency-sensitive |
| single-row insert might get batched along with 10MB worth of inserts from the |
| batch writer, thus delaying the response significantly.<p> |
| |
| Though we currently do not have transactional support, users will be forced |
| to use a AsyncKuduSession to instantiate reads as well as writes. This will make |
| it more straight-forward to add RW transactions in the future without |
| significant modifications to the API.<p> |
| |
| Timeouts are handled differently depending on the flush mode. |
| With AUTO_FLUSH_SYNC, the timeout is set on each apply()'d operation. |
| With AUTO_FLUSH_BACKGROUND and MANUAL_FLUSH, the timeout is assigned to a whole batch of |
| operations upon flush()'ing. It means that in a situation with a timeout of 500ms and a flush |
| interval of 1000ms, an operation can be outstanding for up to 1500ms before being timed out.</div> |
