List Datasets

Overview

The list() method allows you to retrieve datasets with comprehensive filtering, sorting, and pagination capabilities. This is essential for managing and organizing your dataset collections.

Examples

Basic Dataset Listing

from keywordsai import KeywordsAI

client = KeywordsAI(api_key="your-api-key")

# Get all datasets
datasets = client.datasets.list()

print(f"Total datasets: {datasets.total}")
print(f"Retrieved: {len(datasets.data)}")

for dataset in datasets.data:
    print(f"- {dataset.name} ({dataset.log_count} logs)")

Pagination

# Get first page
first_page = client.datasets.list(limit=10, offset=0)
print(f"First page: {len(first_page.data)} datasets")

# Get second page
second_page = client.datasets.list(limit=10, offset=10)
print(f"Second page: {len(second_page.data)} datasets")

# Iterate through all pages
def get_all_datasets():
    all_datasets = []
    offset = 0
    limit = 50
    
    while True:
        page = client.datasets.list(limit=limit, offset=offset)
        all_datasets.extend(page.data)
        
        if not page.has_more:
            break
        
        offset += limit
    
    return all_datasets

all_datasets = get_all_datasets()
print(f"Total datasets retrieved: {len(all_datasets)}")

Filtering by Name

# Search for datasets with "support" in the name
support_datasets = client.datasets.list(name="support")
print(f"Found {len(support_datasets.data)} support datasets")

# Search for specific dataset name
specific_dataset = client.datasets.list(name="Customer Support Training")
if specific_dataset.data:
    dataset = specific_dataset.data[0]
    print(f"Found dataset: {dataset.name}")
else:
    print("Dataset not found")

Date Range Filtering

from datetime import datetime, timedelta

# Get datasets created in the last 30 days
thirty_days_ago = (datetime.now() - timedelta(days=30)).isoformat()
recent_datasets = client.datasets.list(created_after=thirty_days_ago)

print(f"Datasets created in last 30 days: {len(recent_datasets.data)}")

# Get datasets created in January 2024
january_start = "2024-01-01T00:00:00Z"
january_end = "2024-02-01T00:00:00Z"

january_datasets = client.datasets.list(
    created_after=january_start,
    created_before=january_end
)

print(f"Datasets created in January 2024: {len(january_datasets.data)}")

Metadata Filtering

# Filter by single metadata field
training_datasets = client.datasets.list(
    metadata_filter={"purpose": "training"}
)

print(f"Training datasets: {len(training_datasets.data)}")

# Filter by multiple metadata fields
high_quality_support = client.datasets.list(
    metadata_filter={
        "category": "support",
        "quality_level": "high"
    }
)

print(f"High-quality support datasets: {len(high_quality_support.data)}")

# Complex metadata filtering
production_datasets = client.datasets.list(
    metadata_filter={
        "environment": "production",
        "status": "active"
    }
)

for dataset in production_datasets.data:
    print(f"Production dataset: {dataset.name}")
    print(f"  Logs: {dataset.log_count}")
    print(f"  Last updated: {dataset.updated_at}")

Sorting Options

# Sort by creation date (newest first)
newest_datasets = client.datasets.list(
    sort_by="created_at",
    sort_order="desc"
)

# Sort by name alphabetically
alphabetical_datasets = client.datasets.list(
    sort_by="name",
    sort_order="asc"
)

# Sort by log count (largest first)
largest_datasets = client.datasets.list(
    sort_by="log_count",
    sort_order="desc"
)

print("Largest datasets:")
for dataset in largest_datasets.data[:5]:  # Top 5
    print(f"  {dataset.name}: {dataset.log_count} logs")

# Sort by last update (most recently updated first)
recently_updated = client.datasets.list(
    sort_by="updated_at",
    sort_order="desc"
)

print("Recently updated datasets:")
for dataset in recently_updated.data[:3]:  # Top 3
    print(f"  {dataset.name}: {dataset.updated_at}")

Combined Filtering and Sorting

recent_training = client.datasets.list(
    created_after="2024-01-01T00:00:00Z",
    metadata_filter={"purpose": "training"},

Advanced Use Cases

Dataset Analytics

def analyze_datasets():
    # Get all datasets
    all_datasets = client.datasets.list(limit=1000)
    
    # Calculate statistics
    total_logs = sum(d.log_count for d in all_datasets.data)

Dataset Search and Discovery

def search_datasets(query, search_fields=None):
    if search_fields is None:
        search_fields = ["name", "description"]
    
    # Search by name
    name_results = client.datasets.list(name=query) if "name" in search_fields else None
    
    # For description search, we need to get all datasets and filter
    # (assuming API doesn't support description search directly)

results = search_datasets("customer support")
print(f"Found {len(results)} datasets matching 'customer support'")

for dataset in results:
    print(f"  {dataset.name}: {dataset.description[:100]}...")

Dataset Monitoring

def monitor_dataset_growth():
    from datetime import datetime, timedelta
    
    # Get datasets created in different time periods
    now = datetime.now()
    periods = {
        "last_24h": now - timedelta(hours=24),

        "last_month": now - timedelta(days=30)
    }
    
    growth_stats = {}
    
    for period_name, start_time in periods.items():
        datasets = client.datasets.list(
            created_after=start_time.isoformat(),
            limit=1000
        )
        
        growth_stats[period_name] = {
            "count": len(datasets.data),
            "total_logs": sum(d.log_count for d in datasets.data)
        }

    return growth_stats

# Monitor growth

Batch Operations

def process_datasets_in_batches(batch_size=10):
    offset = 0
    processed_count = 0
    
    while True:
        # Get batch of datasets
        batch = client.datasets.list(limit=batch_size, offset=offset)
        
        if not batch.data:
            break
        
        # Process each dataset in the batch
        for dataset in batch.data:
            # Example processing: check if dataset needs updating
            if dataset.log_count > 1000 and not dataset.metadata.get("large_dataset"):
                print(f"Large dataset detected: {dataset.name} ({dataset.log_count} logs)")
                # Could update metadata here

        offset += batch_size
    
    print(f"Total datasets processed: {processed_count}")

# Process all datasets in batches
process_datasets_in_batches()

Error Handling

Basic Error Handling

from keywordsai.exceptions import ValidationError, RateLimitError

def list_datasets_safely(**kwargs):
    try:
        datasets = client.datasets.list(**kwargs)
        return datasets
    except ValidationError as e:
        print(f"Validation error: {e}")
        return None
    except RateLimitError:
        print("Rate limit exceeded. Please retry later.")
        return None
    except Exception as e:
        print(f"Unexpected error: {e}")
        return None

# Use safe listing
datasets = list_datasets_safely(limit=50, sort_by="created_at")
if datasets:
    print(f"Retrieved {len(datasets.data)} datasets")
else:
    print("Failed to retrieve datasets")

Retry Logic for Listing

import time

def list_datasets_with_retry(max_retries=3, **kwargs):
    for attempt in range(max_retries):
        try:
            datasets = client.datasets.list(**kwargs)
            return datasets
        except RateLimitError:
            if attempt < max_retries - 1:
                wait_time = 2 ** attempt
                print(f"Rate limited. Retrying in {wait_time} seconds...")
                time.sleep(wait_time)
            else:
                print("Rate limit exceeded. Max retries reached.")
                return None
        except Exception as e:
            print(f"Error (attempt {attempt + 1}): {e}")
            if attempt < max_retries - 1:
                time.sleep(1)
            else:
                return None
    
    return None

# Use retry logic
datasets = list_datasets_with_retry(limit=100, sort_by="log_count")

Best Practices

Efficient Pagination

def efficient_dataset_iteration(process_func, batch_size=50):
    """Efficiently iterate through all datasets with a processing function."""
    offset = 0
    total_processed = 0
    
    while True:
        try:
            batch = client.datasets.list(limit=batch_size, offset=offset)
            
            if not batch.data:
                break
            
            # Process batch
            for dataset in batch.data:
                process_func(dataset)
                total_processed += 1
            
            print(f"Processed {len(batch.data)} datasets (total: {total_processed})")

            print(f"Error processing batch at offset {offset}: {e}")
            break
    
    return total_processed

# Example usage
def analyze_dataset(dataset):

        return datasets
    
    def clear_cache(self):
