2024-01-20 14:07:58 +03:00
Vitaliy Filippov 1025d1c777 Implement min/max list_count to make listings during performance test reasonable 2024-01-20 14:07:58 +03:00
Vitaliy Filippov f4cd609bd7 Fix and improve parallel allocation
- Do not try to allocate more DB blocks in an inode block until it's "confirmed" and "locked" by the first write
- Do not recheck for new zero DB blocks on first write into an inode block - a CAS failure means someone else is already writing into it
- Throw new allocation blocks away regardless of whether the known_version is 0 on a CAS failure
2024-01-20 14:07:58 +03:00
Vitaliy Filippov 2ded2f08b4 Implement key_prefix for K/V stress test 2024-01-20 14:07:58 +03:00
Vitaliy Filippov 8aff78dfa7 More fixes
- do not overwrite a block with older version if known version is newer
  (read may start before update and end after update)
- invalidated block versions can't be remembered and trusted
- right boundary for split blocks is right_half when diving down, not key_lt
- restart update also when block is "invalidated", not just on version mismatch
- copy callback in listings to avoid closure destruction bugs too

Vitaliy Filippov 2272573883 Experiment: transform offsets for better sharding 2024-01-20 14:07:58 +03:00
Vitaliy Filippov 5d3515d66b More post-stress-test fixes
- Prevent _split types of new blocks
- Stop updating new blocks only after the whole update, otherwise pointers
  may become invalid
- Use recheck_none for updates initially
- Use UINT64_MAX as initial block version when postponing ops, otherwise the
  check fails when the block is initially empty. This for example leads to
  writing both leaf items & block pointers (which is incorrect) into the root
  block when starting stress-test with --parallelism 32
- Fix -EINTR comparison

Vitaliy Filippov 544af504f7 K/V fixes after stress-test :-)
- track block versions correctly - per inode block (128kb) instead of tree block (4kb)
- prevent multiple parallel CAS writes of the same inode block
- add logging for EILSEQ which means invalid data in the tree
- fix get_block updated flag which was true for blocks already in cache and was leading to infinite loops on "unrelated block" errors
- apply changes to blocks in cache only after successful writes (using "virtual changes")
- do not replace cached block with an older version from disk
- recheck "unrelated blocks" (read/update collisions) until data stops changing
- track tree path correctly - do not treat split block as parent of its right half
- correctly move blocks when finding new empty place on disk
- restart updates from the beginning when one of blocks is changed by a parallel update
- fix delete using SET opcode and setting key to the empty value instead
- prevent changing the same key more than 1 time in parallel
- fix listing verification
- resume continue_updates in update_find (required because it uses continue_update itself)
- add allow_old_cached parameter to get()

EC/XOR setups:
EC/XOR setups (EC N+K):
- Single-threaded (T1Q1) read latency: 1.5 network roundtrips + 1 disk read.
- Single-threaded write+fsync latency:
- With immediate commit: 3.5 network roundtrips + 1 disk read + 2 disk writes.
- With lazy commit: 5.5 network roundtrips + 1 disk read + 2 disk writes + 2 disk fsyncs.
- 0.5 in actually (k-1)/k which means that an additional roundtrip doesn't happen when
- 0.5 in actually `(N-1)/N` which means that an additional roundtrip doesn't happen when
the read sub-operation can be served locally.
- Saturated parallel read iops: min(network bandwidth, sum(disk read iops)).
- Saturated parallel write iops: min(network bandwidth, sum(disk write iops * number of data drives / (number of data + parity drives) / write amplification)).
In fact, you should put disk write iops under the condition of ~10% reads / ~90% writes in this formula.
- Linear read: `min(total network bandwidth, sum(disk read MB/s))`.
- Linear write: `min(total network bandwidth, sum(disk write MB/s * N/(N+K)))`.
- Saturated parallel read iops: `min(total network bandwidth, sum(disk read iops))`.
- Saturated parallel write iops: roughly `total iops / (N+K) / WA`. More exactly,
`min(total network bandwidth * N/(N+K), sum(disk randrw iops / (N*4 + K*5 + 1)))` with
random read/write mix corresponding to `(N-1)/(N*4 + K*5 + 1)*100 % reads`.
- For example, with EC 2+1 it is: `(7% randrw iops) / 14`.
- With EC 6+3 it is: `(12.5% randrw iops) / 40`.
