+The `taskLimits` field can be used with the `equalDistribution`,
`fillCapacity`, `equalDistributionWithCategorySpec` and
`fillCapacityWithCategorySpec` strategies.
+If you don't provide it, it will default to not being used.

+|Property|Description|Default|
+|--------|-----------|-------|
+|`taskLimits`|A map where each key is a task type (`String`), and the
corresponding value represents the absolute limit on the number of task slots
that tasks of this type can occupy. The value is an `Integer` that is greater
than or equal to 0. For example, a value of 5 means that tasks of this type can
occupy up to 5 task slots in total. If both absolute and ratio limits are
specified for the same task type, the effective limit will be the smaller of
the absolute limit and the limit derived from the corresponding ratio.
`taskLimits = {"index_parallel": 3, "query_controller": 5}`. In this example,
parallel indexing tasks can occupy up to 3 task slots, and query controllers
can occupy up to 5 task slots.|`{}`|
+|`taskRatios`|A map where each key is a task type (`String`), and the
corresponding value is a `Double` which should be in the range [0, 1],
representing the ratio of available task slots that tasks of this type can
occupy. This ratio defines the proportion of total task slots a task type can
use, calculated as `ratio * totalSlots`. If both absolute and ratio limits are
specified for the same task type, the effective limit will be the smaller of
the absolute limit and the limit derived from the corresponding ratio.
`taskRatios = {"index_parallel": 0.5, "query_controller": 0.25}`. In this
example, parallel indexing tasks can occupy up to 50% of the total task slots,
and query controllers can occupy up to 25% of the total task slots.|`{}`|
