lintel::db::PoolSettings Struct Reference

#include <ConnectionPool.h>

Public Attributes
std::size_t	maxConnections = 0
std::chrono::milliseconds	acquireTimeout { 5000 }

Detailed Description

Tuning of a ConnectionPool.

maxConnections encodes three operating modes with one implementation:

value	behaviour
0	no pool; acquire() fails, the registry keeps no entry
1	one persistent connection, serialized between callers (SQLite default)
N>1	bounded pool (PostgreSQL default, parallel HTTP threads)
