We have just released version 0.1 of the Foreign Data Wrapper for InfluxDB.
This release can work with PostgreSQL 9.6, 10 and 11.
This release supports following features :
- WHERE clauses including timestamp, interval and now functions are pushed down
- Simple aggregation without GROUP BY are pushed down
Limitations
- INSERT, UPDATE and DELETE are not supported.
- Result sets have different number of rows depending on specified target list.
- Complex boolean conditions not allowed in InfluxDB like WHERE b = (a = true) may cause error.
- Conditions including NULL may cause error.
This is developed by Toshiba Software Engineering & Technology Center.
Please see the repository for details.
