From 6c9190a1868edd1798e1b2c48decac25ec106594 Mon Sep 17 00:00:00 2001 From: Tobias Schottdorf Date: Fri, 4 Nov 2016 07:08:58 -0400 Subject: [PATCH] storage: fork-lift proposer-evaluated KV MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #6290. Add experimental proposer-evaluated KV gated behind the environment variable `COCKROACH_PROPOSER_EVALUATED_KV`. When set to a truthy value, Raft proposals are evaluated and the resulting RocksDB `WriteBatch` submitted to Raft along with some auxiliary metadata. The result of the evaluation is only stored in the pending command on the proposer, and returned to the waiting client after the `WriteBatch` has been applied. Introduce a natural failfast path for (most) proposals returning an error. Instead of proposing, waiting for Raft, and only then receiving an error, proposals which do not lead to a state change receive their error directly when the proposal is evaluated, upstream of Raft. Only errors which still want to persist data (for instance, `*TransactionRetryError` when intents were laid down) go through the whole proposal, with the client receiving the error after the associated `Batch` commits. While proposer-evaluated KV is now ready for review, preliminary testing and benchmarking, the current implementation is incomplete and incorrect: - `Lease` acquisition is not special-cased, meaning that lease state may be clobbered freely when non-leaseholders propose a lease request based on stale data. This needs to be fixed but it also shows that we don't stress that scenario sufficiently in testing yet. - Similarly, we don't check that commands can only apply under the lease that they were proposed (which is necessary). - `CommandQueue` does not account for internal keys accessed by overlapping commands correctly (this is tracked in #10084), which in principle also lead to anomalies which should be exposed by testing and addressed. Instead, **every** command inserts a span that covers everything. Horrible for performance, great for correctness; #10084 needs to address this. - `TestingCommandFilter` needs to be refactored to be an explicit interceptor for the pre-Raft stage of commands. Tests were fixed up enough to pass with proposer-evaluated KV as well, but it's possible that some tests don't test what they used to. Benchmark results for non-proposer-evaluated-KV against `master` below. **Note that all of them have the "correctness hack" in `(*Replica).beginCmds` disabled; not doing that should give much worse results but we don't care about those in practice** We pay a small fee in allocations, but nothing appears outrageous. So from a performance perspective, this PR seems safe to merge: ``` $ for br in exp-prop-kv masterdo git checkout $br && make bench COCKROACH_PROPOSER_EVALUATED_KV=false PKG=./sql TESTS='(Select|Insert|Update|Delete)1[0-9]*_Cockroach' TESTFLAGS='-benchmem -count 10' BENCHTIMEOUT=1h > $(git rev-parse --abbrev-ref HEAD); done $ benchstat master exp-prop-kv name old time/op new time/op delta Select1_Cockroach-24 79.8µs ± 2% 79.7µs ± 3% ~ (p=0.912 n=10+10) Insert1_Cockroach-24 500µs ± 3% 520µs ± 5% +4.12% (p=0.001 n=10+10) Insert10_Cockroach-24 665µs ± 3% 667µs ± 3% ~ (p=0.631 n=10+10) Insert100_Cockroach-24 1.77ms ± 5% 1.78ms ± 4% ~ (p=0.529 n=10+10) Insert1000_Cockroach-24 11.9ms ± 3% 11.9ms ± 2% ~ (p=1.000 n=10+10) Update1_Cockroach-24 727µs ± 2% 732µs ± 6% ~ (p=0.971 n=10+10) Update10_Cockroach-24 1.14ms ± 4% 1.15ms ± 3% ~ (p=0.211 n=9+10) Update100_Cockroach-24 4.53ms ±12% 4.46ms ± 6% ~ (p=0.796 n=10+10) Update1000_Cockroach-24 33.8ms ± 4% 32.9ms ± 3% -2.60% (p=0.019 n=10+10) Delete1_Cockroach-24 674µs ± 2% 671µs ± 2% ~ (p=0.796 n=10+10) Delete10_Cockroach-24 812µs ± 2% 828µs ± 2% +2.01% (p=0.003 n=9+10) Delete100_Cockroach-24 2.35ms ± 1% 2.39ms ± 5% ~ (p=0.094 n=9+9) Delete1000_Cockroach-24 17.0ms ± 4% 17.0ms ± 2% ~ (p=0.853 n=10+10) InterleavedSelect1000_Cockroach-24 52.7ms ± 4% 52.8ms ± 5% ~ (p=0.549 n=10+9) name old alloc/op new alloc/op delta Select1_Cockroach-24 7.31kB ± 0% 7.31kB ± 0% +0.03% (p=0.000 n=10+9) Insert1_Cockroach-24 36.6kB ± 0% 40.0kB ± 0% +9.25% (p=0.000 n=10+10) Insert10_Cockroach-24 85.2kB ± 0% 90.5kB ± 0% +6.14% (p=0.000 n=10+10) Insert100_Cockroach-24 538kB ± 0% 543kB ± 0% +0.96% (p=0.000 n=10+9) Insert1000_Cockroach-24 4.63MB ± 0% 4.64MB ± 0% +0.09% (p=0.002 n=10+10) Update1_Cockroach-24 62.2kB ± 0% 65.5kB ± 0% +5.37% (p=0.000 n=8+10) Update10_Cockroach-24 136kB ± 0% 142kB ± 0% +3.95% (p=0.000 n=10+9) Update100_Cockroach-24 863kB ± 0% 865kB ± 0% +0.29% (p=0.000 n=9+9) Update1000_Cockroach-24 7.15MB ± 0% 7.15MB ± 0% ~ (p=0.065 n=9+10) Delete1_Cockroach-24 54.0kB ± 0% 57.3kB ± 0% +6.15% (p=0.000 n=10+10) Delete10_Cockroach-24 64.4kB ± 0% 67.9kB ± 0% +5.49% (p=0.000 n=10+10) Delete100_Cockroach-24 173kB ± 0% 178kB ± 0% +2.87% (p=0.000 n=10+9) Delete1000_Cockroach-24 1.19MB ± 0% 1.14MB ± 0% -3.72% (p=0.000 n=9+10) InterleavedSelect1000_Cockroach-24 797kB ± 0% 797kB ± 0% ~ (p=0.811 n=10+10) name old allocs/op new allocs/op delta Select1_Cockroach-24 111 ± 0% 111 ± 0% ~ (all equal) Insert1_Cockroach-24 386 ± 0% 395 ± 0% +2.33% (p=0.000 n=9+8) Insert10_Cockroach-24 612 ± 0% 622 ± 0% +1.63% (p=0.000 n=8+8) Insert100_Cockroach-24 2.63k ± 0% 2.64k ± 0% +0.36% (p=0.000 n=10+7) Insert1000_Cockroach-24 22.6k ± 0% 22.6k ± 0% +0.05% (p=0.006 n=10+10) Update1_Cockroach-24 682 ± 0% 691 ± 0% +1.32% (p=0.000 n=10+10) Update10_Cockroach-24 1.01k ± 0% 1.02k ± 0% +0.96% (p=0.000 n=10+9) Update100_Cockroach-24 3.99k ± 0% 4.00k ± 0% +0.22% (p=0.000 n=9+9) Update1000_Cockroach-24 31.6k ± 0% 31.6k ± 0% +0.03% (p=0.000 n=9+9) Delete1_Cockroach-24 568 ± 0% 577 ± 0% +1.58% (p=0.000 n=10+8) Delete10_Cockroach-24 693 ± 0% 703 ± 0% +1.46% (p=0.000 n=10+10) Delete100_Cockroach-24 1.83k ± 0% 1.84k ± 0% +0.55% (p=0.000 n=9+10) Delete1000_Cockroach-24 12.7k ± 0% 12.7k ± 0% ~ (p=0.954 n=10+10) InterleavedSelect1000_Cockroach-24 3.11k ± 0% 3.11k ± 0% ~ (p=0.586 n=10+7) ``` `master` vs proposer-evaluated KV.
