Ingest FLUXNET data into a DuckDB database

Source: R/flux_duckdb.R
flux_db_build.Rd

[Experimental] As an alternative to reading FLUXNET data into memory with flux_read(), this ingests all FLUXNET data into a DuckDB database that can be queried in R with dplyr via dbplyr. This is especially useful for daily and hourly data which are likely to overflow memory when trying to read them in with flux_read().

Usage

flux_db_build(
  manifest,
  duckdb_path = Sys.getenv("FLUXNET_DB_PATH", unset = "fluxnet/fluxnet.duckdb")
)

Arguments

manifest

A file manifest tibble created by flux_discover_files().

duckdb_path

File path to a .duckdb file used to store FLUXNET data. Can be set with the environment variable FLUXNET_DB_PATH.

Value

Returns nothing; called for side-effects only.

Note

Currently "BIF" and "BIFVARINFO" CSV files are not included in the DuckDB database.
