T\u00e4iendavalt v\u00f5ib m\u00e4rkida SynchDB 1.0 laienduse v\u00e4ljalaskmist, mis on ette n\u00e4htud PostgreSQL andmete replikeerimiseks \u00fche v\u00f5i mitme kolmanda osapoole andmebaasidest, nagu MySQL, MS SQLServer ja Oracle. Sellised v\u00e4listud andmebaasid toimivad andmeallikatena, mis kantakse otse PostgreSQL-i p\u00f5hisesse sihtandmebaasi, ilma et oleks vaja t\u00e4iendavaid kihtide kasutamist andmete s\u00fcnkroonimisprotsessi orkestreerimiseks (k\u00f5ik s\u00fcnkroonimisprotsessid t\u00f6\u00f6tleb SynchDB laiendus). Projekti kood on kirjutatud C ja Java keeltes ning levitatakse Apache 2.0 litsentsi alusel. SynchDB 1.0 on m\u00e4rgitud projekti esimeseks stabiilseks v\u00e4ljalaskeks. <\/p>\n
S\u00fcsteem koosneb kuuest komponendist: <\/p>\n
- \n
- Debezium Runner Engine — Java p\u00f5hine mootor, mis pakub mooduleid andmebaaside muutuste andmete voogude t\u00f6\u00f6tlemiseks erinevatest DBMSidest (MySQL, MS SQLServer ja Oracle) ning edastab saadud andmed universaalses JSON-formaadis.\n
- SynchDB Worker — k\u00e4ivitab Debezium Runner Engine'i eksemplare konkreetsete DBMSide andmete replikatsiooniks, v\u00f5tab neist vastu muutused JSON-formaadis ja edastab Format Converter moodulile.\n
- SynchDB Launcher — loob ja l\u00f5petab SynchDB t\u00f6\u00f6tlejaid, kasutades PostgreSQL API-d taustprotsesside k\u00e4ivitamiseks.\n
- Format Converter — anal\u00fc\u00fcsib JSON-formaadis muudatuste voogu, muundab v\u00e4liseid andmet\u00fc\u00fcpe ja DDL-p\u00e4ringuid PostgreSQL-i \u00fchilduvateks t\u00fc\u00fcpideks ja p\u00e4ringuteks.\n
- Replication Agent — t\u00f6\u00f6tleb Format Converterist saadud HeapTupleData formaadis v\u00e4ljundi ja k\u00e4ivitab meetodid, et sisestada andmeid PostgreSQL-i.\n
- Table Synch Agent (arendamisel) — pakub t\u00f5husat meetodit tabelite algsama s\u00fcnkroniseerimise jaoks. <\/ul>\n
