是否存在任何内置库或需要实现自定义库？
我试着在这里检查，但不确定如何从这里开始：bigtable连接池
我尝试了以下代码，但不确定如何继续：

import com.google.cloud.bigtable.config.BigtableOptions;
import com.google.cloud.bigtable.config.CredentialOptions;
import com.google.cloud.bigtable.grpc.BigtableSession;
import com.google.cloud.bigtable.grpc.io.ChannelPool;
import com.mahindra.digisense.config.AppConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.security.GeneralSecurityException;

@Component
public class BigTableConnectionPoolingExample {

    @Autowired
    private AppConfig.BigTableConfig bigTableConfig;

    private void bigTableConnectionPooling() throws IOException, GeneralSecurityException {
        CredentialOptions credentialOptions = CredentialOptions.jsonCredentials(new FileInputStream(new File(bigTableConfig.getCredentialsJson())));
        BigtableOptions.Builder builder = new BigtableOptions.Builder();
        builder.setCredentialOptions(credentialOptions);
        ChannelPool.ChannelFactory channelFactory = (ChannelPool.ChannelFactory) BigtableSession.createChannelPool(bigTableConfig.getInstanceId(), builder.build());
        ChannelPool channelPool = new ChannelPool(channelFactory,3);
    }
}

下面是另一个堆栈溢出问题，没有答案。
