- Rev 36327 2026-04-21 13:35:46
- Author: amit
- Log message:
- Fix currentinventorysnapshot/currentreservationsnapshot deadlock and optimize getFirstBillingDate
- SaholicInventoryServiceImpl: enforce reservation-snapshot → inventory-snapshot
lock order in addReservationCount and reduceReservationCount via explicit
session.flush(); eliminates the hadb1 deadlock recorded 2026-04-20 19:43:24
between these two methods' opposite-order writes.
- SaholicInventorySnapshot: add @DynamicUpdate so UPDATEs only rewrite the
changed column instead of all three — cuts redo/binlog write amplification
and makes deadlock dumps pinpoint the actual business path.
- TransactionRepositoryImpl.getFirstBillingDate: replace filesort-over-all-billed-
orders with MIN(billingTimestamp) via new Order.selectFirstBillingByRetailer
named query (Select tables optimized away). Preserves 2017-01-01 cutoff and
null-for-unbilled-partner semantics.
- Add @Cacheable on redisOneDayCacheManager keyed by fofoId (unless null) so the
8 call sites stop piling up identical SELECTs on the order table — this was
the query pinning Hikari slots at 150-460s each in recent processlist dumps.
