Overall we are satisfied with TiDB adoption. TiDB has many good features I love, here I highlight some top useful features for our company: 1. Finalcial-grade HA; 2. Online elastic expansion and contraction; 3. Support high concurrency and analytics workload; 4. Rich ecosystem of useful tools. Bewertung gesammelt von und auf G2.com gehostet.
1. Lack of data compression capability; 2. TiFlash testing performance is not good enough, and it requies much higher hardware resource. Bewertung gesammelt von und auf G2.com gehostet.

There are a lot of useful features. I will bring up the 4 top most useful features for us:
1. MySQL compatibility
2. Built-in high availability
3. Horizontal scaling
4. Built-in CDC (Change Data Capture) Bewertung gesammelt von und auf G2.com gehostet.
At the time this review written, TiDB lack of Postgres compatibility and not support any kind of stored procedure Bewertung gesammelt von und auf G2.com gehostet.
1. It is a fully managed database as a service running on AWS, cost saving for operation and management.
2. On-demand expansion nodes for peak traffic.
3. Mysql ecosystem compatibility.
4. supports processing both TP and AP workloads. Bewertung gesammelt von und auf G2.com gehostet.
1. Sometimes it may causes higher resource consumption for smaller workloads scenario.
2. Currently does not support azure. Bewertung gesammelt von und auf G2.com gehostet.
Easy to use because it is highly compatible with MySQL protocol, reduces the costs of operations and migration.
It can consolidate all upstream MySQL instance data in one TiDB cluster, we do not need to care about underlying data sharding.
One-stack HTAP simplifies the data stack.
And good technical support. Bewertung gesammelt von und auf G2.com gehostet.
For some complex analysis queries, the pressure of TiKV storage resource is still relatively large.
Lack of robust resource control capabilities in current v6 version. Bewertung gesammelt von und auf G2.com gehostet.
1. The distributed architecture provides seamless scalability, making the data platform more agile.
2. One stack real-time HTAP capability
3. It is compatible with MySQL protocol, we do not change the app codes.
4. Avoid the cloud vendor lock-in, and the support team is good. Bewertung gesammelt von und auf G2.com gehostet.
1. The sync diff function is imperfect and cannot compare the json and timestamp fields.
2. There is no mechanism for redirecting to TiKV when TiFlash is down, it will cause some query problems. Bewertung gesammelt von und auf G2.com gehostet.
