yamcsadmin rocksdb bench¶

NAME

yamcsadmin rocksdb bench - Benchmark RocksDB storage engine

SYNOPSIS

yamcsadmin rocksdb bench [--dbDir DIR] [--baseTime TIME]
    [--count COUNT] [--duration HOURS]

OPTIONS

--dbDir DIR¶

Directory where the database will be created. A “rocksbench” archive instance will be created in this directory

--baseTime TIME¶

Start inserting data with this time. Default: 2017-01-01T00:00:00

--count COUNT¶

The partition counts for the 5 frequencies: [10/sec, 1/sec, 1/10sec, 1/60sec and 1/hour]. It has to be specified as a string (use quotes).

--duration HOURS¶

The duration in hours of the simulated data. Default: 24

DESCRIPTION

The benchmark consists of a table load and a few selects. The table is loaded with telemetry packets received at frequencies of [10/sec, 1/sec, 1/10sec, 1/60sec and 1/hour]. The table will be identical to the tm table and will contain a histogram on pname (= packet name). It is possible to specify how many partitions (i.e. how many different pnames) to be loaded for each frequency and the time duration of the data.
