Technical Annotations (41)

Configuration Parameters (7)
iterator.chunk_sizerecommended: 1000
number of records to process per batch, prevents loading entire queryset into memory
chunk_sizerecommended: 2000 (default), tune down for wide rows, up for narrow ones
Controls how many rows .iterator() fetches at once from database cursor
memory_limit_mbrecommended: 500
memory threshold for monitoring and alerting
page_sizerecommended: 50
Default pagination size for list endpoints when client doesn't specify
statement_timeoutrecommended: 10000
PostgreSQL query timeout in milliseconds to kill runaway queries
CACHES.BACKENDrecommended: django.core.cache.backends.locmem.LocMemCache
local-memory backend unsuitable for production multi-process setups
CACHES.default.BACKENDrecommended: django.core.cache.backends.redis.RedisCache or django.core.cache.backends.memcached.MemcachedCache
Use shared backend instead of locmem for production
Error Signatures (3)
