Methods:

`emit`(record)	Do whatever it takes to actually log the specified logging record.
`acquire`()	Acquire the I/O thread lock.
`addFilter`(filter)	Add the specified filter to this handler.
`close`()	Tidy up any resources used by the handler.
`createLock`()	Acquire a thread lock for serializing access to the underlying I/O.

Attributes:

name

emit(record)¶

Do whatever it takes to actually log the specified logging record.

This version is intended to be implemented by subclasses and so raises a NotImplementedError.

acquire()¶: Acquire the I/O thread lock.

addFilter(filter)¶: Add the specified filter to this handler.

close()¶

Tidy up any resources used by the handler.

This version removes the handler from an internal map of handlers, _handlers, which is used for handler lookup by name. Subclasses should ensure that this gets called from overridden close() methods.

createLock()¶: Acquire a thread lock for serializing access to the underlying I/O.

filter(record)¶

Determine if a record is loggable by consulting all the filters.

The default is to allow the record to be logged; any filter can veto this and the record is then dropped. Returns a zero value if a record is to be dropped, else non-zero.

Changed in version 3.2: Allow filters to be just callables.

flush()¶

Ensure all logging output has been flushed.

This version does nothing and is intended to be implemented by subclasses.

format(record)¶

Format the specified record.

If a formatter is set, use it. Otherwise, use the default formatter for the module.

get_name()¶

handle(record)¶

Conditionally emit the specified logging record.

Emission depends on filters which may have been added to the handler. Wrap the actual emission of the record with acquisition/release of the I/O thread lock. Returns whether the filter passed the record for emission.

handleError(record)¶

Handle errors which occur during an emit() call.

This method should be called from handlers when an exception is encountered during an emit() call. If raiseExceptions is false, exceptions get silently ignored. This is what is mostly wanted for a logging system - most users will not care about errors in the logging system, they are more interested in application errors. You could, however, replace this with a custom handler if you wish. The record which was being processed is passed in to this method.

property name¶

release()¶: Release the I/O thread lock.

removeFilter(filter)¶: Remove the specified filter from this handler.

setFormatter(fmt)¶: Set the formatter for this handler.

setLevel(level)¶: Set the logging level of this handler. level must be an int or a str.

fiftyone.operators.is_new(release_date, days=30)¶

Determines if a feature is considered “new” based on its release date.

A feature is considered new if its release date is within the specified number of days.

Examples:

is_new("2024-11-09")
# True if today's date is within 30 days after 2024-11-09

is_new(datetime(2024, 11, 9), days=15)
# True if today's date is within 15 days after November 9, 2024

is_new("2024-10-01", days=45)
# False if today's date is more than 45 days after October 1, 2024

Parameters

release_date –
the release date of the feature, in one of the following formats:
- a string in the format "%Y-%m-%d", e.g., "2024-11-09"
- a datetime instance
days (30) – the number of days for which the feature is considered new

Returns

True/False whether the release date is within the specified number of days

fiftyone.operators.execution_cache(_func=None, *, residency='hybrid', max_size=None, ttl=None, link_to_dataset=True, key_fn=None, store_name=None, version=None, operator_scoped=False, user_scoped=False, prompt_scoped=False, jwt_scoped=False, collection_name=None, serialize=None, deserialize=None)¶

Decorator for caching function results in an ExecutionStore.

The function must:

accept a ctx argument as the first parameter
return a serializable value
should produce the same output for the same input
should have no side effects
have serializable parameters and return values

Parameters

ttl (None) – Time-to-live for the cached value in seconds.
link_to_dataset (True) – Whether to tie the cache entry to the dataset
key_fn (None) – A custom function to generate cache keys. If not provided, the function arguments are used as the key by serializing them as JSON.
store_name (None) – Custom name for the execution store. Defaults to the function name.
version (None) – Set a version number to prevent cache collisions when the function implementation changes.
operator_scoped (False) – Whether to tie the cache entry to the current operator
user_scoped (False) – Whether to tie the cache entry to the current user
prompt_scoped (False) – Whether to tie the cache entry to the current operator prompt
jwt_scoped (False) – Whether to tie the cache entry to the current user’s JWT
collection_name (None) – Override the default collection name for the execution store used by the execution_cache. The default collection name is “execution_store”.
serialize (None) – Custom serialization function given the original value that returns a JSON-serializable value.
deserialize (None) – Custom deserialization given a JSON-serializable value and returns the original value.
residency ("hybrid") –
The residency of the cache. Can be one of: - “transient”: Cache is stored in the execution store with policy=”evict”. - “ephemeral”: Cache is stored in memory and is cleared when the process ends. - “hybrid”: (default) Combination of transient and ephemeral. Cache is stored in memory

and in the execution store. The memory cache is used first, and if the value is not found, it falls back to the execution store.
max_size (None) – Maximum size of the memory cache. Only applicable for “ephemeral” and “hybrid” residency modes. If not provided, the default size is 1024. The cache will evict the least recently used items when the size exceeds this limit.

note:

When using ``link_to_dataset=True``:
    - the associated store is deleted the dataset is deleted
    - the cache entry is namespaced to the dataset

note:

Return values will be coerced from JSON unsafe types to safe types.
This may yield unexpected return values if the cached function returns
non-serializable types (e.g., NumPy arrays), since they are converted
to a JSON-compatible format.

This behavior can be overridden by providing custom ``serialize`` and/or
``deserialize`` functions.

Example Usage:

# Standalone function with default caching @execution_cache def expensive_query(ctx, path):

return ctx.dataset.count_values(path)

# Instance method with dataset-scoped caching class Processor:

@execution_cache(ttl=60, store_name=”processor_cache”) def expensive_query(self, ctx, path):

return ctx.dataset.count_values(path)

# Using a custom key function def custom_key_fn(ctx, path):

return [path, get_day_of_week()]

# Combines the custom key function with user-scoped caching @execution_cache(ttl=90, key_fn=custom_key_fn, jwt_scoped=True) def user_specific_query(ctx, path):

return ctx.dataset.match(
F(“creator_id”) == ctx.user_id

).count_values(path)

# Bypass the cache result = expensive_query.uncached(ctx, path)

# Set the cache for the given arguments expensive_query.set_cache(ctx, path, value_to_cache)

# Clear the cache for the given arguments expensive_query.clear_cache(ctx, path)

# Remove all cache entries for the function expensive_query.clear_all_caches()

# Clear all cache entries for the function expensive_query.clear_all_caches()

# NOTE: dataset_id is required if link_to_dataset=True expensive_query.clear_all_caches(dataset_id=dataset._doc.id)
