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	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.

Felipe Renan	f8797a2058	Fix realtime address balance update ... The balance update stopped working because the client was trying to subscribe twice in the channel topic. When the server receives a duplicated subscription, he closes the first connection to open a new one. In our case, the client subscribed in the address channel in address.js and again address/transactions.js, then the server was keeping only the last subscription.	6 years ago

Sebastian Abondano	fa09f399d8	GraphQL API token_transfers query ... Why: * For GraphQL API users to be able to fetch token transfer events. RPC API users could use this instead of the `tokentx` RPC API action. Example usage: 1. ``` query ($token_contract_address_hash: AddressHash!, $first: Int!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first) { edges { node { amount block_number log_index token_id from_address_hash to_address_hash token_contract_address_hash transaction_hash } } } } ``` 2. with pagination support via [Relay Cursor Connections](https://facebook.github.io/relay/graphql/connections.htm) ``` query ($token_contract_address_hash: AddressHash!, $first: Int!, $after: ID!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first, after: $after) { page_info { has_next_page has_previous_page } edges { node { amount from_address_hash to_address_hash } cursor } } } ``` * Issue link: n/a This change addresses the need by: * Editing the node interface and node field in `BlockScoutWeb.Schema` to support token transfers. * Adding `token_transfers` connection field to root query object in `BlockScoutWeb.Schema` * Making `token_transfer` object types a node type and adding a few new fields to it, in `BlockScoutWeb.Schema.Types`. * Creating `BlockScoutWeb.Resolvers.TokenTransfer` with resolver functions for getting token transfers. * Adding `get_token_transfer/1` and `list_token_transfers_query/1` to `Explorer.GraphQL`. These two functions are used by the new resolver functions mentioned above. * Editing RPC API docs to reference the new GraphQL query field added in this commit.	6 years ago
Sebastian Abondano	e7071172e2	Allows other sites to open blockscout in iframe ... Why: * For our partners to be able to open BlockScout in an iframe. * Issue link: n/ah This change addresses the need by: * Creating `AllowIframe` plug. * Editing router to have a new scope for write-only routes and a separate one for read-only routes which allows for iframes (using the plug mentioned above).	6 years ago
