Dodatno je mogu\u0107e napomenuti izdavanje pro\u0161irenja SynchDB 1.0, koje je namenjeno replikaciji podataka iz jedne ili vi\u0161e spoljnih SDB kao \u0161to su MySQL, MS SQLServer i Oracle u PostgreSQL. Ove spoljne SDB su izvori podataka, koji se direktno prenose u jednu ciljnu bazu podataka zasnovanu na PostgreSQL, bez kori\u0161\u0107enja dodatnih slojeva za orkestraciju procesa sinhronizacije podataka (sve operacije sinhronizacije obra\u0111uju se pro\u0161irenjem SynchDB). Kod projekta je napisan na jezicima C i Java i distribuira se pod licencom Apache 2.0. SynchDB 1.0 je ozna\u010den kao prvo stabilno izdanje projekta. <\/p>\n
Sistem se sastoji od \u0161est komponenti: <\/p>\n
- \n
- Debezium Runner Engine — motor v Javi, ki nudi module za obdelavo podatkovnih sprememb iz razli\u010dnih SGBD (MySQL, MS SQLServer in Oracle) in pretvarjanje prejetih podatkov v univerzalni format JSON.\n
- SynchDB Worker — za\u017eene primerke Debezium Runner Engine za replikacijo podatkov iz dolo\u010denih SGBD, sprejema njihove spremembe v formatu JSON in jih posreduje modulu Format Converter.\n
- SynchDB Launcher — ustvarja in zaklju\u010duje delo obdelovalcev SynchDB, uporablja API PostgreSQL za zagon ozadjevnih procesov.\n
- Format Converter — analizira tok sprememb v formatu JSON, pretvarja zunanje tipe podatkov in DDL poizvedbe v tipe in poizvedbe, zdru\u017eljive s PostgreSQL.\n
- Replication Agent — obdeluje izhod v formatu HeapTupleData iz Format Converter in za\u017eene metode za vstavljanje podatkov v PostgreSQL.\n
- Table Synch Agent (v razvoju) — zagotavlja u\u010dinkovit na\u010din za\u010detne sinhronizacije tabel. <\/ul>\n
