# mongoc_client_pool_min_size()

## Synopsis

    void
    mongoc_client_pool_min_size (mongoc_client_pool_t *pool,
                                 uint32_t min_pool_size)
       BSON_GNUC_DEPRECATED;

This function sets the maximum number of idle clients to be kept in the pool. Any idle clients in excess of the maximum are destroyed. This function is deprecated because its behavior does not match what developers expect from a “minimum pool size”, and its actual behavior is likely to hurt performance.

Applications should not call this function, they should instead accept the default behavior, which is to keep all idle clients that are pushed into the pool.

## Parameters

- `pool`: A mongoc_client_pool_t.
- `min_pool_size`: The number of idle clients to keep in the pool.

## Thread Safety

This function is safe to call from multiple threads.

Subsequent calls to mongoc_client_pool_push() respect the new minimum size, and close the least recently used mongoc_client_t if the minimum size is exceeded.

Created using Sphinx 1.6.5, based on Sphinx Readable Theme.
