View Source GoogleApi.BigtableAdmin.V2.Model.ColumnFamilyStats (google_api_bigtable_admin v0.22.0)

Approximate statistics related to a single column family within a table. This information may change rapidly, interpreting these values at a point in time may already preset out-of-date information. Everything below is approximate, unless otherwise specified.

Attributes

  • averageCellsPerColumn (type: float(), default: nil) - How many cells are present per column qualifier in this column family, averaged over all rows containing any column in the column family. e.g. For column family "family" in a table with 3 rows: A row with 3 cells in "family:col" and 1 cell in "other:col" (3 cells / 1 column in "family") A row with 1 cell in "family:col", 7 cells in "family:other_col", and 7 cells in "other:data" (8 cells / 2 columns in "family") * A row with 3 cells in "other:col" (0 columns in "family", "family" not present) would report (3 + 8 + 0)/(1 + 2 + 0) = 3.66 in this field.
  • averageColumnsPerRow (type: float(), default: nil) - How many column qualifiers are present in this column family, averaged over all rows in the table. e.g. For column family "family" in a table with 3 rows: A row with cells in "family:col" and "other:col" (1 column in "family") A row with cells in "family:col", "family:other_col", and "other:data" (2 columns in "family") * A row with cells in "other:col" (0 columns in "family", "family" not present) would report (1 + 2 + 0)/3 = 1.5 in this field.
  • logicalDataBytes (type: String.t, default: nil) - How much space the data in the column family occupies. This is roughly how many bytes would be needed to read the contents of the entire column family (e.g. by streaming all contents out).
