Description

Implemented the pooled SQLite db connection for the DHT storage in favour of the Rust based async read-write lock, which makes use of the much faster SQLite3 Write-ahead Log (WAL) mode.

Motivation and Context

Recent changes to the common implementation for SQLite pooled connections managed in the background via Diesel and SQLite3 enabled this improvement.

How Has This Been Tested?

  • Unit tests
  • Cucumber tests
  • System-level tests [Edit: Running a twice more intensive stress test than before (2x sender wallets with 3x 1000 transactions on one computer to 3x receiver wallets on another computer vs. 1x sender wallet with 3x 1000 transactions to 3x receiver wallets) the disk resource utilization was 90+% down from previous levels - ~100% disk utilization on both systems during all phases of the transactions life cycle down to <~5% with occasional spikes up to ~80%. All transactions reached mined confirmed in all 5 participating wallets.)

Looks good, A little concerned about blocking tokio task scheduling with synchronous calls, but understand that may be tricky with pooled connections. Let's see if we end up with any perf issues - it's in the wallet, so will probably be fine.

@sdbondi see edit about stress test results monitoring disk utilization. The change actually affects both the base node's and the wallet's DHT dedup databases.

@hansieodendaal I'm happy about using a WAL - was talking specifically about tokio scheduler blocking, but if the calls are quick enough it shouldn't have a negative impact. I expect it will be fine.

EDIT: oh just saw the updated PR description - LGTM

@hansieodendaal Just need to address the infinite recursion in PartialEq
