Compiled or vectorized queries - which are faster, how do they differ? Here is Everything You Always Wanted to Know About Compiled and Vectorized Queries But Were Afraid to Ask 👉
Difficult to find logic bugs in
#DBMSs
?
@RiggerManuel
, a postdoctoral fellow at ETH Zurich, is an expert in this area. So far, he and his colleague have found 400+ bugs in popular DBMSs, including 50+
#TiDB
bugs. 👏
👀 Learn their experience 👇
Previously, the transaction size in
#TiDB
was limited to 100 MB and the total number of entries to ≤ 300,000. Now TiDB 4.0 sets the transaction size limit to 10 GB so that you can use TiDB in more scenarios.
@nick_r_cameron
shows how we implemented it:
We just open-sourced TiDB-operator, leveraging
#Kubernetes
to deploy/operate/manage a distributed database like TiDB. See tutorial on how you can experiment w/ it on your laptop in
