pip install laila-core

LAILA is a Python platform for unifying training, simulation, and data management into a single computational workflow. It wraps heterogeneous storage backends (S3, GCS, Redis, HDF5, filesystem, and more) behind one consistent API so that memorizing data, recalling it, and orchestrating compute feels the same regardless of where things live.

LAILA is type-free

LAILA is type-free — whatever type you memorize is exactly the type you get back. No serialization boilerplate, no type casting, one interface for everything:

import torch, laila

dict_entry = laila.constant(data={"key": [1, 2, 3]})
laila.memorize(dict_entry)                          # memorize a dict
laila.remember(dict_entry.global_id).data            # returns a dict

tensor_entry = laila.constant(data=torch.randn(128, 64))
laila.memorize(tensor_entry)                         # memorize a tensor
laila.remember(tensor_entry.global_id).data           # returns a tensor

LAILA has a uniform API

The same three verbs — memorize, remember, and forget — work across every storage backend. S3, HDF5, Cloudflare R2, Redis, GCS, filesystem — swap the pool, keep the code:

from laila.pool import S3Pool, HDF5Pool, CloudflarePool

s3_pool = S3Pool(...)
hdf5_pool = HDF5Pool(...)
cf_pool = CloudflarePool(...)

laila.memory.extend(s3_pool, pool_nickname="s3")
laila.memory.extend(hdf5_pool, pool_nickname="hdf5")
laila.memory.extend(cf_pool, pool_nickname="cloudflare")

entry = laila.constant(data=torch.randn(128, 64))

laila.memorize(entry, pool_nickname="s3")          # write to S3
laila.memorize(entry, pool_nickname="hdf5")        # write to HDF5
laila.memorize(entry, pool_nickname="cloudflare")  # write to Cloudflare R2

laila.remember(entry.global_id, pool_nickname="s3")          # read from S3
laila.remember(entry.global_id, pool_nickname="hdf5")        # read from HDF5
laila.remember(entry.global_id, pool_nickname="cloudflare")  # read from Cloudflare R2

laila.forget(entry.global_id, pool_nickname="s3")          # delete from S3
laila.forget(entry.global_id, pool_nickname="hdf5")        # delete from HDF5
laila.forget(entry.global_id, pool_nickname="cloudflare")  # delete from Cloudflare R2

LAILA has async operations

Every operation returns a future you can wait on synchronously or await asynchronously:

future = laila.memorize(entry)
laila.wait(future)    # blocking
await future          # or async

Quick example

Stack a fast local cache in front of remote storage with a single operator. Reads cascade through the chain until they find the data, caching a copy in every tier on the way back up.

import laila
from laila.pool import S3Pool, HDF5Pool

# Create an HDF5 pool (local disk) and an S3 pool (remote)
hdf5_pool = HDF5Pool(nickname="cache_hdf5")
s3_pool = S3Pool(
    bucket_name="your-bucket",
    access_key_id="YOUR_ACCESS_KEY_ID",
    secret_access_key="YOUR_SECRET_ACCESS_KEY",
    region_name="us-east-1",
    nickname="origin_s3",
)

# Register both pools with LAILA's memory system
laila.memory.extend(hdf5_pool, pool_nickname="cache_hdf5")
laila.memory.extend(s3_pool, pool_nickname="origin_s3")

# Wire a three-tier proxy chain: memory → HDF5 → S3
laila.alpha_pool << hdf5_pool << s3_pool

# Store an entry directly in S3
entry = laila.constant(data={"msg": "hello from S3"}, nickname="proxy_demo")
future = laila.memorize(entry, pool_nickname="origin_s3")
laila.wait(future)

print(laila.alpha_pool.exists(entry.global_id))  # False — not cached yet

# Read through the alpha pool — cascades to S3, caches on the way back
blob = laila.alpha_pool[entry.global_id]

print(laila.alpha_pool.exists(entry.global_id))  # True  — cached in memory
print(hdf5_pool.exists(entry.global_id))          # True  — cached on disk
print(s3_pool.exists(entry.global_id))            # True  — the origin

Installation extras

Install only the backends you need:

pip install "laila-core[s3]"        # S3 / Cloudflare R2 / Backblaze B2
pip install "laila-core[redis]"     # Redis
pip install "laila-core[hdf5]"      # HDF5
pip install "laila-core[torch]"     # PyTorch tensor support
pip install "laila-core[all]"       # everything

Logging

LAILA ships with a single process-wide logger (laila.logger) that emits structured records into the standard library logging hierarchy rooted at "laila". It has two independent sinks:

• stdout (a stderr StreamHandler), gated by the display flag.
• pool, gated by pool_nickname / pool_id, which writes every record into the pool as a JSON Entry.

The two sinks are not mutually exclusive: with display=True and a pool configured you get both. When no pool is set, display is forced to True so records are never silently dropped.

import laila

# Default level is DEBUG; with no pool, stdout is forced on.
laila.enable_logging()

# Pool only - records flow to the pool, stdout stays quiet (display=False default).
laila.enable_logging("INFO", pool_nickname="audit_hdf5")

# Pool plus stdout - both sinks active.
laila.enable_logging("INFO", pool_nickname="audit_hdf5", display=True)

# Configure via laila.args (CLI-style, mirrored under args.environment.logger)
laila.args.logger = {"enabled": True, "level": "DEBUG", "pool_nickname": "audit_hdf5"}

Each record is a JSON-trivial dict with ts, level, event, a free-form extra bag, and the global_id of every actor involved (policy, pool, entry, future, taskforce). When pool_nickname (or pool_id) is set, records round-trip through the same laila.memorize / laila.remember verbs as any other data. The logger is a singleton (laila.logger always returns the same instance) and inherits from the same CLI-capable / identifiable bases as other LAILA subsystems, so its config appears in laila.args.environment.logger.

Vision

LAILA is intended to serve as an interdisciplinary platform for teams that need to move fluidly between data creation, data storage, model training, and large-scale execution. Rather than treating infrastructure boundaries as the primary abstraction, LAILA focuses on ergonomic syntax and reusable interfaces that let users reason about workflows at a higher level.

This approach makes it easier to:

• organize and manage data across multiple storage systems
• connect compute and memory workflows with less boilerplate
• build distributed pipelines that remain readable and maintainable
• reduce the operational friction between experimentation and production-scale execution

Current release

LAILA is currently in beta 1.0.

The current release includes the command and memory module as the first public component of the broader platform. Interfaces may continue to evolve as the platform expands and real-world usage informs the next stage of development.
