* rename * set agent address * refactor * add agent sub * pub messages * grpc new client * can publish records via agent * send init message with session id * fmt * check cancelled request while waiting * use sessionId * handle possible nil stream * subscriber process messages * separate debug port * use atomic int64 * less logs * minor * skip io.EOF * rename * remove unused * use saved offsets * do not reuse session, since always session id is new after restart remove last active ts from SessionEntry * simplify printing * purge unused * just proxy the subscription, skipping the session step * adjust offset types * subscribe offset type and possible value * start after the known tsns * avoid wrongly set startPosition * move * remove * refactor * typo * fix * fix changed path
