[C++] use customed key-value type

[pentium3]

Hi. In the current implementation I found that both keys and values are uint64_t. https://github.com/microsoft/FASTER/blob/master/cc/benchmark-dir/benchmark.cc#L104

How could I modify to support 1KB string type value?

Thanks

The test samples show how to use larger and/or variable-length keys and values. For example, see this one:

FASTER/cc/test/in_memory_test.cc

Line 322 in c8bf594

TEST(InMemFaster, UpsertRead_Concurrent) {

You will need to modify the benchmark yourself to handle this along such lines.

Thanks. Do you support user-defined key size as well?

[badrishc]

Yes, in the linked test page there is an example with custom keys.

Thanks. Do you mena in this example?

FASTER/cc/test/in_memory_test.cc

Line 1911 in c8bf594

TEST(InMemFaster, UpsertRead_VariableLengthKey) {

what's the difference between Key and ShallowKey in this case?

Not sure, you need to go through all samples.
