On January 20th, 2018, a chilly Saturday in the middle of the winter, more than 200 coders, hackers, and techies streamed into Garage Café, a chic coffee shop in the heart of Beijing’s techhub, Zhongguancun. They weren’t there to get coffee. They weren’t there to stay warm. They were there to be part of TiDB DevCon 2018, a technology party for the developers, by the developers.

On January 19th, one day before DevCon, TiDB 1.1 Alpha was released with the following improvements:
alter table t shard_row_id_bits = 4and is also able to handle millions of TPS.
load data local infile 'output.csv' into table xxx;
With TiDB Lightning, it takes less than 5 hours to import 1 TB of raw SQL file from MySQL to TiDB–10x faster than before.
Deploying a TiDB cluster is much easier than ever before. Developers can use Docker Compose to launch a local TiDB cluster with one command on their laptops and play around with it. Moreover, the container-based components of TiDB managed by a special software named tidb-operator can be simply deployed and maintained on a Kubernetes environment in production.
TiDB Syncer is a smart tool to migrate data from MySQL to TiDB in real-time. It poses as a MySQL slave and listens to the changes of master by parsing the MySQL Binary Logs, and replaying the changes sequentially on the TiDB instance.
TiDB Binlog is a tool designed to help users to synchronize data to downstream database in real-time. For example, users can use TiDB binlog to synchronize data from one TiDB instance to another as a Hot-backup cluster. In addition, TiDB Binlog can also be used for other purposes, such as incremental backup, message triggering and subscription or driving stream computing and analytics.
TiDB Lightning is a high-speed data importing tool, customized for TiDB:
Wormhole is an enterprise edition tool for data synchronization. It contains the following features:
Wormhole–Enterprise synchronization tool
TiDB Insight provides users with a real-time visualization and overview into the region distribution, leader regions status, hotspots, region & leader transfer, traffic flow, and the health of the entire cluster.
The TiDB monitoring system collects metrics from TiDB cluster and is integrated with Grafana to visualize data. Alerts are defined based on Prometheus's flexible query language. And the alerting system can keep users informed of any abnormal status in their TiDB cluster via email, SMS, Slack messages, or other customized ways.
