Ayrat Badykov	ca309afaa7	add error field to token instances	5 years ago
Ayrat Badykov	ddda3026b6	optimize token token transfers query ... the longes part of the query is ordering. Removing order clause from the query makes a query much faster. It's because by default indexes are ordered in ASC order	5 years ago
Ayrat Badykov	2de98bf627	add indexes for token instances fetching queries ... Without these indexes the query can not be finished. But on staging requests for `tokenURI` are timing out. That's why we have so many records with empty metadata.	5 years ago

Ayrat Badykov	eef64e47b5	optimize ERC721 inventory query ... Inventory tab for ERC721 doesn't load any token transfers because query is timing out. Looking into the query, it does a couple of unnessary joins: 1. with `transactions` for `block_number`. But token_transfers already have block_number 2. with `tokens` to check if `token_transfers` are for ERC-721 token. But the query is only executed only for ERC 721 tokens One more issue that I found is that the query uses distinct by `token_id`. But we don't have any indexes on `token_id`. So this PR adds index on `token_id`.	5 years ago

pasqu4le	1f5bf98a06	Add script to validate internal_transactions constraint for large DBs ... Problem: executing the existing sql script to validate internal_transactions constraint is too slow (or even gets stuck) for large DBs and its progress cannot be checked. Solution: add an alternative implementation of the same script that can be monitored from outside and has better performance.	5 years ago

pasqu4le	728d25bcf4	Add consensus filter to AddRefetchNeededToBlock migration ... It is unnecessary to set `refetch_needed` to blocks that do not yet have a consensus, so this small change can save some time in the migration and avoid some checking from the temporary fetcher.	6 years ago

pasqu4le	64acef7b71	Add temporary indexer worker to remove consensus on blocks with mismatching transactions ... After the solution for #1991 it is necessary to remove consensus from blocks whose number of transactions mismatch compared to a node, so that these blocks are refetched.	6 years ago
goodsoft	b9cc8a417f	Force block refetch if transaction is recollated in a different block ... Due to race conditions described in #1911 transactions from a consensus block might get overwritten by the same transactions from a non-consensus block. To prevent this we force a block refetch (by marking it as non-consensus), if a transaction belonging to it gets overwritten by the same transaction from a different block.	6 years ago

goodsoft	5512531527	Make block size field nullable ... Uncle block API returns null values for block size, and we need to properly store them in the database.	6 years ago
goodsoft	8e6ee4ceb1	Use eth_getUncleByBlockHashAndIndex for uncle block fetching ... Parity returns `null` for many uncle blocks, if they are fetched using `eth_getBlockByHash`. This is most probably caused by the fact that Parity only keeps full block data for recent non-consensus blocks. This causes uncle_block fetcher to loop endlessly trying to fetch "missing" blocks, hogging both app server and Parity resources. Instead, we use `eth_getUncleByBlockHashAndIndex` method, which works for all uncle blocks. As we didn't previously store index of an uncle block within a nephew block, a new field and a temporary fixup fetcher is added to get the index from nephew blocks.	6 years ago

goodsoft	ea7d0d007f	Optimize token holder count updates when importing address current balances ... Problem: realtime fetcher transactions takes too long and often fails with a timeout. The reason of timeout is deleted_address_current_token_balances step of import, which selects previous balances for the rows we are going to update. The SELECT query it makes is extremely slow. Solution: we incorporate fetching old balance value into the upsert itself. This is done by help of a transient old_value field, which is updated in ON CONFLICT clause of INSERT with the previous value and returned.
