We have released PGSpider extension v1.0.0.
This is an extension to construct data virtualization engine by PostgreSQL.
As compared to the first release of 10 months ago, the quality and connectivity of FDWs were improved.
Please refer README.md for supporting FDWs.
The main feature is
Node partitioned table
User can get records in multi tables on some data sources by one SQL easily. If there are some tables with similar schema in each data source, PGSpider can view them as a single virtual table.
PGSpider executes queries and fetches results from child nodes in parallel. PGSpider expands a virtual table to child tables, access corresponding datasource of each child table on some worker processes.
PGSpider can pushdown WHERE clause and aggregation functions to data sources. The shippability depends on datasource FDW.
This is developed by Toshiba Software Engineering & Technology Center.
