Athena
-
Amazon Athena is an interactive query service that lets you use standard SQL
to analyze data directly in Amazon S3. You can point Athena at your data in
Amazon S3 and run ad-hoc queries and get results in seconds. Athena is
serverless, so there is no infrastructure to set up or manage. You pay only
for the queries you run. Athena scales automatically—executing queries in
parallel—so results are fast, even with large datasets and complex queries.
For more information, see What is
Amazon Athena in the Amazon Athena User Guide.

type.

EncryptionConfiguration
-
If query results are encrypted in Amazon S3, indicates the encryption option
used (for example,
SSE-KMS
or CSE-KMS
) and key
information.

NamedQuery
-
A query, where
QueryString
is the list of SQL query statements
that comprise the query.
-
QueryExecution
-
Information about a single instance of a query execution.
-
QueryExecutionContext
-
The database and data catalog context in which the query execution occurs.
-
QueryExecutionStatistics
-
The amount of data scanned during the query execution and the amount of time
that it took to execute, and the type of statement that was run.
-
QueryExecutionStatus
-
The completion date, current state, submission time, and state change reason
(if applicable) for the query execution.
-
ResultConfiguration
-
The location in Amazon S3 where query results are stored and the encryption
option, if any, used for query results. These are known as "client-side
settings". If workgroup settings override client-side settings, then the
query uses the workgroup settings.
-
ResultConfigurationUpdates
-
The information about the updates in the query results, such as output
location and encryption configuration for the query results.
-
ResultSet
-
The metadata and rows that comprise a query result set. The metadata
describes the column structure and data types. To return a
ResultSet
object, use GetQueryResults.
-
ResultSetMetadata
-
The metadata that describes the column structure and data types of a table
of query results. To return a
ResultSetMetadata
object, use
GetQueryResults.
-
Row
-
The rows that comprise a query result table.
-
StartQueryExecutionOutput
-
-
StopQueryExecutionOutput
-
-
TableMetadata
-
Contains metadata for a table.
-
Tag
-
A label that you assign to a resource. In Athena, a resource can be a
workgroup or data catalog. Each tag consists of a key and an optional value,
both of which you define. For example, you can use tags to categorize Athena
workgroups or data catalogs by purpose, owner, or environment. Use a
consistent set of tag keys to make it easier to search and filter workgroups
or data catalogs in your account. For best practices, see Tagging
Best Practices. Tag keys can be from 1 to 128 UTF-8 Unicode characters,
and tag values can be from 0 to 256 UTF-8 Unicode characters. Tags can use
letters and numbers representable in UTF-8, and the following characters: +

-
-
UnprocessedNamedQueryId
-
Information about a named query ID that could not be processed.
-
UnprocessedQueryExecutionId
-
Describes a query execution that failed to process.

-

UpdateWorkGroupOutput
-
-
WorkGroup
-
A workgroup, which contains a name, description, creation time, state, and
other configuration, listed under WorkGroup$Configuration. Each
workgroup enables you to isolate queries for you or your group of users from
other queries in the same account, to configure the query results location
and the encryption configuration (known as workgroup settings), to enable
sending query metrics to Amazon CloudWatch, and to establish per-query data
usage control limits for all queries in a workgroup. The workgroup settings
override is specified in EnforceWorkGroupConfiguration (true/false) in the
WorkGroupConfiguration. See
WorkGroupConfiguration$EnforceWorkGroupConfiguration.
-
WorkGroupConfiguration
-
The configuration of the workgroup, which includes the location in Amazon S3
where query results are stored, the encryption option, if any, used for
query results, whether the Amazon CloudWatch Metrics are enabled for the
workgroup and whether workgroup settings override query settings, and the
data usage limits for the amount of data scanned per query or per workgroup.
The workgroup settings override is specified in
EnforceWorkGroupConfiguration (true/false) in the WorkGroupConfiguration.
See WorkGroupConfiguration$EnforceWorkGroupConfiguration.
-
WorkGroupConfigurationUpdates
-
The configuration information that will be updated for this workgroup, which
includes the location in Amazon S3 where query results are stored, the
encryption option, if any, used for query results, whether the Amazon
CloudWatch Metrics are enabled for the workgroup, whether the workgroup
settings override the client-side settings, and the data usage limit for the
amount of bytes scanned per query, if it is specified.
-
WorkGroupSummary
-
The summary information for the workgroup, which includes its name, state,
description, and the date and time it was created.
