TableStatsResponse class
Approximate statistics related to a table. These statistics are calculated infrequently, while simultaneously, data in the table can change rapidly. Thus the values reported here (e.g. row count) are very likely out-of date, even the instant they are received in this API. Thus, only treat these values as approximate. IMPORTANT: Everything below is approximate, unless otherwise specified.

TableStatsResponse({required Input<
double> averageCellsPerColumn, required Input<double> averageColumnsPerRow, required Input<String> logicalDataBytes, required Input<String> rowCount}) -
Creates a new TableStatsResponse.
averageCellsPerColumnHow many cells are present per column (column family, column qualifier) combinations, averaged over all columns in all rows in the table. e.g. A table with 2 rows: * A row with 3 cells in "family:col" and 1 cell in "other:col" (4 cells / 2 columns) * A row with 1 cell in "family:col", 7 cells in "family:other_col", and 7 cells in "other:data" (15 cells / 3 columns) would report (4 + 15)/(2 + 3) = 3.8 in this field.averageColumnsPerRowHow many (column family, column qualifier) combinations are present per row in the table, averaged over all rows in the table. e.g. A table with 2 rows: * A row with cells in "family:col" and "other:col" (2 distinct columns) * A row with cells in "family:col", "family:other_col", and "other:data" (3 distinct columns) would report (2 + 3)/2 = 2.5 in this field.logicalDataBytesThis is roughly how many bytes would be needed to read the entire table (e.g. by streaming all contents out).rowCountHow many rows are in the table.const -

Properties
-
averageCellsPerColumn
→ Input<
double> -
How many cells are present per column (column family, column qualifier) combinations, averaged over all columns in all rows in the table. e.g. A table with 2 rows: * A row with 3 cells in "family:col" and 1 cell in "other:col" (4 cells / 2 columns) * A row with 1 cell in "family:col", 7 cells in "family:other_col", and 7 cells in "other:data" (15 cells / 3 columns) would report (4 + 15)/(2 + 3) = 3.8 in this field.
final
-
averageColumnsPerRow
→ Input<
double> -
How many (column family, column qualifier) combinations are present per row in the table, averaged over all rows in the table. e.g. A table with 2 rows: * A row with cells in "family:col" and "other:col" (2 distinct columns) * A row with cells in "family:col", "family:other_col", and "other:data" (3 distinct columns) would report (2 + 3)/2 = 2.5 in this field.

-
The hash code for this object.
