         * - a counter that limits attempts to select server and checkout a connection before we created a batch;
         * - a counter per each batch that limits attempts to execute the specific batch.
         * Fortunately, these counters do not exist concurrently with each other. While maintaining the counters manually,
         * we must adhere to the contract of `RetryingSyncSupplier`. When the retry timeout is implemented, there will be no counters,
