Should Partition Handles be kept around? #142

Pretty much what the title says, I'm thinking of using fjall for a project but the docs do not make it clear if I should keep around the partition handles I instance (I.e. share them throuhg an Arc<Mutex<...>>) or instance on each time I need to access a given partition? Thanks in advance, this project looks really nice. |

All open partitions are stored in the keyspace behind a RwLock. If the partition(s) you are using are fixed at runtime, holding onto the handle skips going through that lock each time, also it avoids the construction cost of an You can also keep them (or possibly a subset) in your own RwLock (do not use a Mutex), if you have a dynamic (sub)set of partitions during runtime. |
