Highlights of Recent PRs
db#5176 Experimental SKIPPING INDEX
We are thrilled to announce our newest cutting-edge index type, SKIPPING INDEX, which can accelerate query by a lot, especially on high-cardinality scenarios, with a relatively small storage overhead. Notice that this experimental index is in the early preview phase.
db#5208 PostgreSQL as New Meta Storage Option
After the election feature is implemented, we can now use PostgreSQL-compatible RDS as our meta storage, providing a new option against etcd.
db#5288 Grafana Loki JSON Write Protocol
We have supported Grafana Loki gRPC write protocol for a while. This time we add support for JSON protocol as well so that users can shift from Loki to GreptimeDB more easily.
db#5250 COPY TO with SELECT Query
We can now write SELECT query in the COPY TO clause, for example:
sql
COPY (select host, cpu, ts from demo where host = 'host2') TO '/tmp/export/demo.parquet';db#5112 db#4890 db#5203 db#5251 db#5234 Enhanced Flow Usability and Error Handling
In the past weeks, we've devoted ourselves to making Flow easier to use. Now it has better in-time validations, more informative error messages, and more intelligent type inference.
db#5273 db#5254 Critical Bug Fixes
Two edge cases may lead to unexpected behavior. Specifically in concurrent automatic table alteration. Though these cases are hard to meet, we still recommend upgrading our latest release v0.11.2.
