Django MariaDB-Galera Perfermance on K8s
INSERT one row at a time is slow. These are faster:
- Batched insert (many rows in a single
INSERT). Recommend 100 to 1000 rows at a time. LOAD DATA INFILE
The Query Cache slows down inserts. Anyway, it is not allowed on Galera.
How far apart (in milliseconds) are the nodes?
These are terribly high, go back to the defaults:
tmp_table_size=2Gmax_heap_table_size=2GSome places specify utf8, some specify utf8mb4. The latter is preferred. The inconsistency may be causing some performance lag.
