Note: These workarounds covered issues in lein-tools-deps 0.3.0-SNAPSHOT. If using 0.4.1 or later, you should not encounter the issues below.

The following provides some workarounds for some issues when using lein-tools-deps from Cursive on macOS.

Path to clojure

By default, the lein-tools-deps plugin won't see /usr/local/bin/clojure when Cursive processes project.clj, as it evidently has a degenerate path.

You will see an error like the following in the IntelliJ Event Log when it tries to process your project.clj file:

;; # EMULATING DATOMIC EXCISION VIA MANUAL DATA MIGRATION

;; This Gist demonstrates a generic way to migrate an entire Datomic database
;; from an existing 'Origin Connection' to a clean 'Destination Connection',
;; while getting rid of some undesirable data and otherwise preserving history.

-- `minus` is saturating subtraction, so this works like we want it to
eq_max : (n, k : Nat) -> maximum k n = plus (n `minus` k) k
eq_max  n     Z    = rewrite minusZeroRight n in rewrite plusZeroRightNeutral n in Refl
eq_max  Z    (S _) = Refl
eq_max (S n) (S k) = rewrite sym $ plusSuccRightSucc (n `minus` k) k in rewrite eq_max n k in Refl

-- The type here says "the result is" padded to (maximum k n), and is padding plus the original

Hi S-------. I'm not an expert in performance benchmarking--I focus on 
correctness and safety--but I have a few pieces of advice here.

0. Pick multiple workloads that cover the gamut of behaviors in each DB.  
*Don't* choose a completely sharded workload for VoltDB. Don't choose a 
purely commutative workload for Cassandra. Cassandra's Paxos 
implementation is slow and a good benchmark will demonstrate 
that--however, it *doesn't* (I think?) require a global coordinator, 
which means it might *scale* better than a single-coordinator system 
like, say, VoltDB. Talk about those differences!
