to look at the new patch set (#20).
Change subject: KUDU-456 Implement AUTO_FLUSH_BACKGROUND flush mode
......................................................................
KUDU-456 Implement AUTO_FLUSH_BACKGROUND flush mode
Implemented AUTO_FLUSH_BACKGROUND for the Kudu C++ client library.
In AUTO_FLUSH_BACKGROUND mode,
the KuduSession::Apply() method blocks if total amount of data
for pending operations reaches the buffer size limit. The limit
on the buffer size can be set by the
KuduSession::SetMutationBufferSpace() method.
The background flush logic checks whether at least one of the
following two conditions is satisfied to determine whether it's time
to flush the accumulated write operations:
* The over-the-watermark criterion: check whether the total size of the
freshly submitted (i.e. not-yet-scheduled-for-flush) write operations
is over the threshold. The threshold can be set as a percentage
of the total buffer size using the
KuduSession::SetMutationBufferFlushWatermark() method.
* The maximum wait time criterion: check whether the current batch
of operations has been accumulating for more than the maximum
wait time. The maximum wait time can be specified in milliseconds
using the KuduSession::SetMutationBufferFlushInterva() method.
A KuduSession object uses RPC messenger's thread pool to monitor
batches' maximum wait time.
This change also addresses the following JIRA issue:
KUDU-1376 KuduSession::SetMutationBufferSpace is not defined
