numeric
type as follows:
numeric
with no specified precision and scale is mapped to NUMBER(38,20)
.numeric
with precision OR scale which is beyond 38 and 37 is mapped to NUMBER(38, 20)
.numeric
with precision AND scale within the above limits is mapped to NUMBER(precision, scale)
.numeric
type as follows:
numeric
with no specified precision and scale is mapped to BIGNUMERIC(38,20)
.numeric
with precision OR scale which is beyond 38 and 37 respectively, is mapped to BIGNUMERIC(38, 20)
.numeric
with precision AND scale within the above limits is mapped to BIGNUMERIC(precision, scale)
.numeric
type as follows:
numeric
with no specified precision and scale is mapped to Decimal(76,38)
.
numeric
with precision OR scale which is beyond 76 and 38 respectively, is mapped to Decimal(76,38)
.numeric
with precision AND scale within the above limits is mapped to Decimal(precision, scale)
.linestring
with only one point) among PostGIS values it pulls, and writes them as null on the destination.
We keep a log of this data and it can be retrieved if needed.
Valid geospatial data is written on BigQuery and Snowflake in Well-Known Text (WKT)
format,
while to PostgreSQL destinations it is written as it is received.
HSTORE
data as JSON
on BigQuery. All intricaces of the HSTORE
data type are preserved, such as:
NULL
values. Example: '"a"=>NULL'
will be written as {"a":null}
'""=>1'
will be written as {"":1}
'"a"=>"1", "a"=>"2"'
will be written as {"a":2}
VARIANT
data type, although it is
formatted as a JSON
and can be queried as such - snowflake_hstore_column:key
.
null
values from BigQuery arrays. This is because BigQuery does not support null
values in arrays during their insertion.
