# 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]. ### String handling. SORT does not take any locale into account. ## Expiry ranges. Expirations are limited to 8 years. For commands with millisecond precision like PEXPIRE or PSETEX, expirations greater than 2^28ms are quietly rounded to the nearest second losing precision of less than 0.001%. ## Lua We use lua 5.4.4 that has been released in 2022. That means we also support [lua integers](https://github.com/redis/redis/issues/5261).
