Inoltre, si pu\u00f2 notare il rilascio dell'estensione SynchDB 1.0, progettata per la replica dei dati in PostgreSQL da uno o pi\u00f9 DBMS esterni, come MySQL, MS SQLServer e Oracle. Questi DBMS esterni fungono da fonti di dati, che vengono trasferiti direttamente in un'unica database target basato su PostgreSQL, senza l'uso di ulteriori strati per orchestrare il processo di sincronizzazione dei dati (tutte le operazioni di sincronizzazione vengono gestite dall'estensione SynchDB). Il codice del progetto \u00e8 scritto in linguaggi C e Java e viene distribuito sotto licenza Apache 2.0. SynchDB 1.0 \u00e8 segnalato come il primo rilascio stabile del progetto. <\/p>\n
Il sistema include sei componenti: <\/p>\n
- \n
- Debezium Runner Engine \u00e8 un motore Java che fornisce moduli per l'elaborazione dei flussi di cambiamento dei dati da diversi DBMS (MySQL, MS SQLServer e Oracle) e per la traduzione dei dati ricevuti in un formato universale JSON.\n
- SynchDB Worker avvia istanze di Debezium Runner Engine per la replica dei dati da specifici DBMS, riceve le modifiche in formato JSON e le trasmette al modulo Format Converter.\n
- SynchDB Launcher crea e termina i gestori di SynchDB, utilizzando l'API PostgreSQL per avviare processi in background.\n
- Format Converter analizza il flusso di cambiamenti in formato JSON, converte i tipi di dati e le query DDL esterne in tipi e query compatibili con PostgreSQL.\n
- Replication Agent elabora l'output in formato HeapTupleData dal Format Converter e avvia i metodi per l'inserimento dei dati in PostgreSQL.\n
- Table Synch Agent (in fase di sviluppo) \u2014 fornisce un metodo efficace per la sincronizzazione iniziale delle tabelle. <\/ul>\n
