PDNS Auth - lmdb backend shard recommendations

[victoredvardsson]

Hello,

I have searched through all discussions and issues trying to find some information on this. But what is the recommended shard configuration when using the lmdb backend? Im looking into using lightstream to replicate lmdb to different instances and using the default value (64) will complicate Lightstream configuration a bit, since each lmdb (shard) needs to be configured separately in the Lightstream configuration.

Our lmdb backend will contain around 3M zones (with DNSSEC) so is there any performance gain in using a lot of shards or can i just stick with 1 shard that will store all records?

Thanks :)

I found this so is the plan to enforce shard=1 in the future? 38eb249

that patch was released with 4.9.0 already. So if you want to use LS, the recommendation is simple: shards=1
