MsSqlDurableStateStore

Defined in: src/persistence/durable-state-stores/MsSqlDurableStateStore.ts:20
DurableStateStore backed by Microsoft SQL Server (mssql).
Behaviour lives in RelationalDurableStateStore; this class supplies the
T-SQL dialect, whose revision-0 insert is an unguarded INSERT, so a
collision arrives as error 2627 rather than zero affected rows. T-SQL has no
ON CONFLICT DO NOTHING, and both alternatives (MERGE, INSERT … WHERE NOT EXISTS) would still have to handle the same race — letting the primary key
report it is shorter and correct under concurrency.

load()
Section titled “load()”load<
S>(persistenceId,_options?):Promise<Option<DurableStateRecord<S>>>
Defined in: src/persistence/relational/RelationalDurableStateStore.ts:124
Load the latest record for persistenceId, or None if none exists.
options.encryption is required when client-side encryption was
used at write time.

upsert()
Section titled “upsert()”upsert<
S>(persistenceId,expectedRevision,state,_options?):Promise<DurableStateRecord<S>>
Defined in: src/persistence/relational/RelationalDurableStateStore.ts:76
Upsert the state for persistenceId. expectedRevision must match the
current stored revision (0 when no record exists yet). Throws
DurableStateConcurrencyError on conflict. Optional options
carry per-call preferences from the caller (e.g. compression /
encryption set on the actor); stores that cannot honour them
silently ignore the field.
