Amanda Sposito	bf46d3ee51	Add BlockScoutWeb.RealtimeEventHandler and Explorer.Chain.Events.Publisher ... * Separate EventHandler according to broadcast_type event, so the frontend realtime does not need to ignore the catchup events.	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

Luke Imhoff	3c0adace16	Include import_id and transaction_id in logger metadata ... When `import_id` and `transaction_id` was added in Logger calls, they were not added to the metadata allowed to be shown and so weren't appearing in the logs.	6 years ago

Luke Imhoff	2ec9600a61	Only query for coin balance when channel connected ... Normally, it is good idea to only query the database once no matter the number of sockets for a channel, but most addresses don't have listeners, so it is cheaper to not query unless the channel is in use. If we start to see popular addresses, con_cache can be used to only do the query once across all connected sockets for the same address.

Luke Imhoff	ac35c4680f	Move error_count out of prose and into metadata ... Having count and error_count in the metadata would allow us to graph one vs the other to see how often we achieve partial retries vs full retries.	6 years ago

Luke Imhoff	2010e90a71	Move block range out of prose and into metadata ... The catchup block range `first_block_number..last_block_number` will set `Logger.metadata(first_block_number: first_block_number, last_block_number: last_block_number)` for errors in `BoundIntervalSupervisor` and tasks in `Catchup.Fetcher`.	6 years ago

Luke Imhoff	fed7d304e2	Include fetcher in logger metadata ... For each fetcher set the `Logger.metadata(fetcher: ...)` to a short semantic name.
