There's no direct linkage between account-update events and transaction-events
Issue is linked with geyser plugin interface
Currently, there's no straightforward way to determine what notify_transaction call is related to particular update_account call. So, there's no simple way to determine what transaction caused what changes in accounts. This issue is especially valuable in case when several transactions modifies single account in the same slot.
Add txn_signature field to ReplicaTransactionInfo structure
This additional field will contain the signature of transaction which caused this account update event. This modification is not bringing significant overhead because all necessary information for such linkage already available inside Accounts::collect_accounts_to_store method
Problem
Slot status can be used of in other scenarios in addition to account information such as transactions, blocks. The current implementation is too tightly coupled.
Summary of Changes
Decouple the slot status notification from accounts notification. Created a new slot status notification module.
Use bulk insertion to Postgres at startup to reduce time taken for initial snapshot restore for postgres plugin. Avoid duplicate writes of accounts at startup. Doing account plugin notification and indexing in parallel.
Improved error handling for postgres plugin to show the real db issues for debug purpose
Added more metrics for postgres plugin.
Refactored plugin centric code out to a sub module from accounts_db and added unit tests
