RO BDB and other DB open options #233

Open elico opened 2 years ago

elico commented 2 years ago

Hey,

I want to use TokyoCabinet and BDB in a ReadOnly mode. It's possible in the underlying library but I do not see any example of how to use these options when opening a DB file. An example for BDB and TokyoCabinet would be helpful.

Thanks

Hi,

Doesn't look like we have an option for that at the moment - we can look at adding it though. In the meantime, you can use the backend option when creating your store to configure TokyoCabinet in the way you would like. For example:

bdb = ::TokyoCabinet::BDB.new
bdb.open('my_database.tch', ::TokyoCabinet::BDB::OREADER) # Sorry if this is not 100% correct
store = Moneta.new(:TokyoCabinet, backend: bdb)
