Highlights of Recent PRs
db#4600 Switch the keyword for invoking administration functions from select to admin
In previous versions, users needed to use select statements to invoke administration functions, such as select flush_table('monitor'). In this patch, select keyword is replaced by admin, such as admin flush_table('monitor').
db#4552 Fix the problem that failed to build full text index when a single SST file is too large
This PR fixes the issue where full-text indexing fails to build successfully when a single SST file contains too many rows, due to only supporting a single segment buffer.
db#4545 Optimize the count performance for append-only table
For tables created with append_mode=true, this PR can speed up count(*) queries to milliseconds.
db#4603 db#4564 Continuously optimize the performance of time series queries
- Optimize
SeriesDivideperformance. - Optimize predicate pushdown support to avoid redundant filterings
Good First Issue
db#4480 Add debug level traces in Mito Engine
The current Trace is not suitable for user performance debugging. More detailed Spans could be added in the Mito Engine, such as the time taken to read data from S3, etc.
Keywords: Mito Engine, Trace
Difficulty: Medium
db#3265 Add more tests for COPY FROM statements
COPY FROM involves loading data from external source, therefore more tests are required to assure its functionality.
Keywords: SQL, Unit Tests, Coverage
Difficulty: Simple
