Hello Kudu Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/3952 to look at the new patch set (#15). 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. KuduSession objects use RPC messenger's thread pool to schedule background flush tasks. In AUTO_FLUSH_BACKGROUND mode, the KuduSession::Apply() method blocks if total amount of data for operations not pushed to server reaches the buffer size limit. The limit on the buffer size can be set by the KuduSession::SetMutationBufferSpace() method. The background flusher 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-waterline criterion: check whether the total size of the freshly submitted (i.e. not-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 previous flush happened more than the maximum wait time ago. The maximum wait time can be specified in milliseconds using the KuduSession::SetMutationBufferFlushInterva() method. This change also addresses the following JIRA issue: KUDU-1376 KuduSession::SetMutationBufferSpace is not defined Change-Id: I34905c30b3aad96f53cf7a1822b1cde6d25f33a8 --- M python/kudu/tests/test_client.py M src/kudu/client/batcher.cc M src/kudu/client/batcher.h M src/kudu/client/client-internal.h M src/kudu/client/client-test.cc M src/kudu/client/client.cc M src/kudu/client/client.h M src/kudu/client/session-internal.cc M src/kudu/client/session-internal.h M src/kudu/client/write_op.cc M src/kudu/client/write_op.h 11 files changed, 1,115 insertions(+), 158 deletions(-) git pull ssh://gerrit.cloudera.org:29418/kudu refs/changes/52/3952/15 -- To view, visit http://gerrit.cloudera.org:8080/3952 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I34905c30b3aad96f53cf7a1822b1cde6d25f33a8 Gerrit-PatchSet: 15 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Dan Burkert <d...@cloudera.com> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Todd Lipcon <t...@apache.org>
