# Differences with Redis

## String lengths, indices.

String sizes are limited to 256MB.
Indices (say in GETRANGE and SETRANGE commands) should be signed 32 bit integers in range
[-2147483647, 2147483648].

## Expiry ranges.
Expirations are limited to 4 years. For commands with millisecond precision like PEXPIRE or PSETEX,
expirations greater than 2^27ms are quietly rounded to the nearest second loosing precision of less than 0.001%.
robustness fixes plus improve support for auxillary commands so we could run tcl tests. GETRANGE - fix out of bounds bug. Add a decorator for "config get" Add a decorator for "function flush" 2022-04-03 19:55:53 +00:00			`# Differences with Redis`

more work on rdb load. 1. Added support of loading of compressed strings. 2. Verified we load expiry info. 3. Extended supported expiry period to 4 years (previously I set 1 year). 2022-04-13 07:50:19 +00:00			`Expirations are limited to 4 years.
