{} is less than {}, set to default value {}.

Error message

{} is less than {}, set to default value {}.

What it means

tabletCountLimitForOnePartition validates the user-provided doris.tablet-size option. If the configured value is below DORIS_TABLET_SIZE_MIN, it logs this warning and resets the value to the minimum, so downstream tablet splitting uses at least the minimum allowed tablets per partition query.

Solutions

1. Set doris.tablet-size to a value >= DORIS_TABLET_SIZE_MIN in the source config
2. Remove the option entirely to use the default value
3. If you want more parallelism, increase tablet count in Doris (bucket_num) instead of lowering tablet-size below the minimum

Example fix

// before
tablet-size = 0
// after
tablet-size = 5  // >= configured minimum

int tabletSize = config.get("tablet-size");
if (tabletSize < DorisSourceOptions.DORIS_TABLET_SIZE_MIN) {
    tabletSize = DorisSourceOptions.DORIS_TABLET_SIZE_MIN; // or drop the option
}

When it happens

Trigger: tabletsSize -> tabletCountLimitForOnePartition is invoked during split enumeration and DorisSourceOptions.DORIS_TABLET_SIZE was set to a value < DORIS_TABLET_SIZE_MIN (e.g. 0, 1, or a negative number).

Common situations: Users setting tablet-size to 1 or 0 hoping for maximum parallelism; config parsed from a property with a wrong unit; copy-pasted configs from older connector versions with different bounds.
