Tuple compression performance¶
Learn about tuple compression to save memory.
Below are the results of a synthetic test that illustrate how tuple compression impacts performance.
The test was carried out on a simple Tarantool space containing 1,000,000 tuples,
each having a field with a sample JSON roughly 1,000 bytes large.
The test compared the speed of running select
and replace
operations on uncompressed and compressed data
as well as the overall data size of the space.
Performance is measured in requests per second.
Compression type | select , RPS |
replace , RPS |
Space size, bytes |
