Hello Yingchun Lai, Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/18945
to look at the new patch set (#12).
Change subject: KUDU-3393 C++ client support split a tablet to mutil ranges
and concurrent scan data
......................................................................
KUDU-3393 C++ client support split a tablet to mutil ranges and concurrent
scan data
I add a param for build 'KuduScanToken', like this :
`
KuduScanTokenBuilder builder(table);
vector<KuduScanToken*> tokens;
ElementDeleter deleter(&tokens);
// set splitSizeBytes
builder.SetSplitSizeBytes(1000);
ASSERT_OK(builder.Build(&tokens));
`
The default value of split_size_bytes is 0, and this means we don't split the
key range
for a tablet.
If the value of split_size_bytes is nonzero, we will try to send a
SplitKeyRangeRPC to
tservers. We may get more tokens than tablets num and the more tokens will help
us scan faster.
