Luke Imhoff	e5e32d693a	Merge pull request #1275 from poanetwork/counters-queries ... Counter the need for counter queries by using COUNT(*) and adding indexes	6 years ago
Luke Imhoff	903d322553	Use index and COUNT(*) for address_to_validation_count ... BlockValidationCounter is not needed once the query is switched to `COUNT(*)` and an index is added for `blocks.miner_hash`. Creating the index on eth60-test took only 12 seconds. ``` 2018-12-21T08:32:46.375 application=ecto_sql [info] == Running 20181221143000 Explorer.Repo.Migrations.CreateBlocksMinerHashIndex.change/0 forward 2018-12-21T08:32:46.375 application=ecto_sql [info] create index blocks_miner_hash_index 2018-12-21T08:32:59.211 application=ecto_sql [info] == Migrated 20181221143000 in 12.8s ``` Before the index both `COUNT(*)` and `COUNT(hash)` (the old usage before 76fc8e0377 in 92f99cac22) take > 800ms, which would have a noticable impact on the UI. ``` sql> SELECT COUNT(*) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:27:43] 1 row retrieved starting from 1 in 906 ms (execution: 889 ms, fetching: 17 ms) sql> SELECT COUNT(hash) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:28:04] 1 row retrieved starting from 1 in 819 ms (execution: 811 ms, fetching: 8 ms) ``` After the index both queries benefited because `COUNT(hash)` was able to use Bitmap Index Scan, but `COUNT(*)` was much better using a normal Index Scan: ``` sql> SELECT COUNT(hash) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:33:43] 1 row retrieved starting from 1 in 776 ms (execution: 768 ms, fetching: 8 ms) sql> SELECT COUNT(*) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:33:55] 1 row retrieved starting from 1 in 130 ms (execution: 120 ms, fetching: 10 ms) ``` The `SELECT` to get a miner_hash takes 54ms alone, so the `COUNT(*)` takes ~70ms, but EXPLAINs take just as long so ~50ms is my latency to eth60-test, meaning the `SELECT COUNT(*)` takes about 20ms plus latency.	6 years ago
Luke Imhoff	f67241cfc0	Use COUNT(*) for count_token_transfers_from_token_hash ... By using `COUNT(*)` instead of `COUNT(column)`, Postgres optimizes the count to use the row count recorded in the index. The ETS counter appeared necessary because in 95de1ebcb0, `COUNT(id)` was being used (95de1ebcb0/apps/explorer/lib/explorer/chain/token_transfer.ex (L138)), which seems reasonable in Ecto as you need some column to count, but in Postgres, it is more efficient to count everything with `*` as it implies "count rows". `COUNT(column)` requires Postgres check if any of the values are `NULL` and it does not optimize the query even if the column is `NOT NULL` in most cases like when the `id` was used. Testing on eth60-test database, `COUNT(*)` took 62ms while `COUNT(column)` (in this case `amount` since the table no longer has `id) took 16s demonstrating the vast speed improvement of `*` counting. ``` sql> SELECT COUNT(*) FROM token_transfers WHERE token_contract_address_hash = ( SELECT token_contract_address_hash FROM token_transfers LIMIT 1) [2018-12-21 07:51:02] 1 row retrieved starting from 1 in 70 ms (execution: 62 ms, fetching: 8 ms) sql> SELECT COUNT(amount) FROM token_transfers WHERE token_contract_address_hash = ( SELECT token_contract_address_hash FROM token_transfers LIMIT 1) [2018-12-21 07:51:43] 1 row retrieved starting from 1 in 16 s 862 ms (execution: 16 s 855 ms, fetching: 7 ms) ```	6 years ago

Zach Daniel	0bda44d0aa	Merge branch 'master' into add-heart-for-restarts	6 years ago
Luke Imhoff	2a4223c2c6	Allow block numbers to exceed missing block search range by > 1 ... Fixes #1266 Issue #1266 was triggered when the recorded block number exceeded the reported max block number as can happen temporary when the node that gives the latest block number is farther behind than the node that gave the block data. The previous `Explorer.Chain.missing_block_number_ranges` query added in #1230 did not account for the max block number in the database exceeding the range max. When this occurs, an errant range was produced by the #1230 query because it chose the greatest of the range and the max block when trying to find the end point for the gap search. The testing did not catch #1266 because the doctests only used block numbers that exceeded the search range, by 1 and the bug did not show up until it was 2 or more. The new query is split into 4 subqueries: 1. missing prefix when range min < min(block.number) 2. missing infix when the blocks aren't in the range at all 3. missing suffix when max(block.number) < range max 4. gaps between existent block numbers This version is also more efficient as there is only a single sort of the outer `UNION ALL` result instead of a sort of real blocks and fake end points for the range. It is able to move the `UNION ALL` up because it doesn't need to produce fake end cap blocks. This positioning of the `UNION ALL` and `ORDER BY` on the outer most query allows for all 4 queries to use `one_consensus_block_at_height` index and either a limit (for `min`/`max`) or a window aggregate (for `lag`), which has minimal, single row cost.	6 years ago
Luke Imhoff	07cb543948	Failing regression test for #1266 ... When the max block number exceeds the search range by more than 1 it causes extra ranges to be calculated and they depend on the max block number instead of the search range.	6 years ago
