fdb move¶

Move the content of one FDB database. This locks the source database, make it possible to create a second database in another root, duplicates all data. Source data are not automatically removed.

This tool is envisaged for migrating data from two different data store (i.e. from a performance to a capacity data store)

Usage¶

fdb move [options] [request1] [request2] ...

Options¶

Database request must match exactly one database.

`--dest`	The absolute or relative path of a FDB root that can contain a copy of the source database (wipe has to be enabled, archival can be disabled)
`--keep`	Keep the source DB
`--delay`	Delay in sec. before start deleting the source DB. The default is 0 sec. (ignored in case of –keep)
`--threads`	Number of concurrent threads moving data to dest DB
`--minimum-keys=string,string,...`	Use these keywords as a minimum set which must be specified
`--raw`	Don’t apply (contextual) expansion and checking on requests
`--ignore-errors`	Ignore errors (report them as warnings) and continue processing wherever possible
`--all`	Visit all FDB databases
`--config=string`	FDB configuration filename

Example¶

This tool is non-destructive (it only copies data), but it affects the status of the source DB by applying locks.

% fdb move class=rd,expver=xxxx,stream=oper,date=20160907,time=0000,domain=g --dest=../fdb/root2 --delay=10 --threads=16
