13.2.6 Counts per table
The following table contains for each table the number of entries contained in Gaia DR3 and, for reference, the size in SI units of each DR3 table in compressed CSV format as available in the bulk download.
This table does not include the tables published in EDR3 that are still applicable for DR3, nor the table gaia_source_lite, which is just a database view of gaia_source with a reduced subset of the columns included in the full table.
