Config path for database storage

[dazoot]

We store the files on a shared drive (cifs mounted).
We have local SSD drives.
Would like to specify the weed volume server to used an alternate folder for database storage.
So instead of storing .idx files on the network drive, store them local on fast SSD.

Which volume index are you using? memory or leveldb?

Well, yes, there will be two writes, one to .dat and one to .idx files.

If in memory, seems no need to store the index on SSD specifically, especially for reads.

[dazoot]

Leveldb.

[chrislusf]

In your case, how large are the SSD and HDD sizes respectively?

[dazoot]

we store 5TB of data.
SSD is 960GB

[chrislusf]

ok. btw: planning to support ssd-only volumes. it is different from your request. would that be useful to your use case?

[dazoot]

Should be configurable:

• data_storage paths
• index_storage paths

So users can choose what suits them better.

Added this feature. Let me know how it works for you.

When starting volume server, use -dir.idx=... for index storage path.
