When calculating statistics for large tables, Greenplum Database creates a smaller table
by sampling the base table. If the table is partitioned, samples are taken from all
partitions.
- If the number of rows in the base table is estimated to be less than the value of the
- gp_statistics_sampling_threshold configuration parameter, the entire
- base table is used to calculate the statistics.
- If a sample table is created, the number of rows in the sample is calculated to provide a
- maximum acceptable relative error. The amount of acceptable error is specified with the
- gp_analyze_relative_error system configuration parameter, which is set
- to .25 (25%) by default. This is usually sufficiently accurate to generate correct query
- plans. If ANALYZE is not producing good estimates for a table column, you
- can increase the sample size by setting the gp_analyze_relative_error
- configuration parameter to a lower value. Beware that setting this parameter to a low
- value can lead to a very large sample size and dramatically increase analyze time.
