ReaderPool

jellytau_lib::storage::db_service

Struct ReaderPool 

Source 
struct ReaderPool {
    idle: Mutex<Vec<Connection>>,
    returned: Condvar,
}
Expand description

Read-only connections, checked out one per query. WAL gives each a snapshot of the last commit, so they never wait for the writer.

Fields§

§idle: Mutex<Vec<Connection>>§returned: Condvar
