# Column codec research harness, tests and benchmark (no backend linked).
#   nice make -j4              build test and bench into $(OUT) (the research tool is opt-in: make research)
#   make research ARGS='-s'    encoding/compressor sizes on order-shaped data (-s adds decode speeds, -k clustered order)
#   make test [N=2]            round trips, adversarial data, corruption fuzz, per-level kernel differential
#   make SANITIZE=1 test       ASan + UBSan build (into $(OUT)-san)
#   make bench                 ratios per policy and decode/filter speeds per SIMD level (under flock /tmp/sift-perf.lock)
# The cpu module stand-in and the random generator are tools/kernels' (shim.c, harness.h); the column kernels the codec runs on are src/col/kern*.c.
# The chunk generators of test.c are src/col/codec_gen.h, the ones of the in-backend regress test (test/sql/colcodec_*.sql) too.
