Why Do We Need an LDBC SNB-Specific Workload Driver?

Tags:
SNB , DRIVER , INTERACTIVE

In a previous 3-part blog series we touched upon the difficulties of executing the LDBC SNB
Interactive (SNB) workload, while achieving good performance and
scalability. What we didn’t discuss is why these difficulties were
unique to SNB, and what aspects of the way we perform workload execution
are scientific contributions - novel solutions to previously unsolved
problems. This post will highlight the differences between SNB and more …

The SNB Driver part 1 post
introduced, broadly, the challenges faced when developing a workload
driver for the LDBC SNB benchmark. In this blog we’ll drill down deeper
into the details of what it means to execute “dependent queries” during
benchmark execution, and how this is handled in the driver. First of
all, as many driver-specific terms will be used, below is a listing of
their definitions. There is no need to read them in …

Up until now we have introduced the
challenges faced when executing the LDBC SNB benchmark, as well as
explained
how some of these are overcome. With the foundations laid, we can now
explain precisely how operations are executed.

Based on the dependencies certain operations have, and on the
granularity of parallelism we wish to achieve while executing them, we
assign a Dependency Mode and an Execution Mode to every operation type.
Using these …

In this multi-part blog we consider the challenge of running the LDBC
Social Network Interactive Benchmark (LDBC SNB) workload in
parallel, i.e. the design of the workload driver that will issue the
queries against the System Under Test (SUT). We go through design
principles that were implemented for the LDBC SNB workload
generator/load tester (simply referred to as driver). Software and
documentation for this driver is available here: …
