Class EffectKeys

java.lang.Object

com.kingsrook.qqq.backend.core.jobs.effects.EffectKeys

public final class EffectKeys
extends Object

The deterministic idempotency key of an effect, and the forms targets need (spec section 2.13): jobId:chunkSeq:rowKey:effectName. A rerun chunk derives the same keys, so the outbox, the provider and the target all dedupe.

Method Summary

Modifier and Type	Method	Description
static String	digest(String key)	A short, URL- and filename-safe digest of a key (SHA-256, hex, 32 chars): for object names, header values and Message-IDs whatever the row key holds.
static String	idempotencyKeyHeader(String key)	The provider Idempotency-Key header value for an effect.
static String	key(Integer jobId, Integer chunkSeq, String rowKey, String effectName)	jobId:chunkSeq:rowKey:effectName.
static String	messageId(String key, String domain)	A fixed RFC 5322 Message-ID for an email effect, so a resend carries the same id and receiving systems (and reconcile lookups) recognize it.
static String	objectName(String prefix, String key, String extension)	A deterministic object name under a prefix: a repeated PUT overwrites the same object instead of creating another.

key

public static String key(Integer jobId,
 Integer chunkSeq,
 String rowKey,
 String effectName)

jobId:chunkSeq:rowKey:effectName.

digest

public static String digest(String key)

A short, URL- and filename-safe digest of a key (SHA-256, hex, 32 chars): for object names, header values and Message-IDs whatever the row key holds.

idempotencyKeyHeader

public static String idempotencyKeyHeader(String key)

The provider Idempotency-Key header value for an effect.

objectName

public static String objectName(String prefix,
 String key,
 String extension)

A deterministic object name under a prefix: a repeated PUT overwrites the same object instead of creating another.

messageId

public static String messageId(String key,
 String domain)

A fixed RFC 5322 Message-ID for an email effect, so a resend carries the same id and receiving systems (and reconcile lookups) recognize it.
