Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

• Fewer rows fit into memory; increased
likelihood of queries spilling to disk
• Check
SVV_TABLE_INFO(max_varchar)
https://docs.aws.amazon.com/redshift/latest/dg/r_SVV_TABLE_INFO.html
16. Goals of distribution

17. Choosing a distribution style
Key
• Large fact tables
• Rapidly changing tables used in
joins
• Localize columns used within
aggregations
All
• Have slowly changing data
• Reasonable size (i.e., few
millions but not 100s of millions
of rows)
• No common distribution key for
frequent joins
• Typical use case: joined
dimension table without a
common distribution key
Even
• Tables not frequently joined or
aggregated
• Large tables without
acceptable candidate keys
18. Table skew
• If data is not spread evenly across slices, "
you have table skew
• Workload is unbalanced: some nodes will word harder
than others
• Query is as fast as the slowest slice…
https://docs.aws.amazon.com/redshift/latest/dg/c_analyzing-table-design.html
19. Goals of sorting
• Physically sort data within blocks and throughout a table
• Enable range scans to ignore blocks by leveraging zone
maps
• Optimal SORTKEY is dependent on:
• Query patterns
• Data profile
• Business requirements
20. COMPOUND
• Most common
• 1st column in compound key
always used
• Prefix / Time-series data
Choosing a SORTKEY
INTERLEAVED
• No common filter criteria
• Key columns are “equivalent”
• No prefix / Non time-series data
• Primarily as a query predicate (date, identifier, …)
• Optionally, choose a column frequently used for aggregates
• Optionally, choose same as distribution key column for most efficient
joins (merge join)
https://docs.aws.amazon.com/redshift/latest/dg/t_Sorting_data-compare-sort-styles.html
21. Compressing data
• COPY automatically analyzes and compresses data when loading
into empty tables
• CREATE TABLE AS supports automatic compression (Nov’16)
• ANALYZE COMPRESSION estimates storage space savings (Nov’16)
• Be careful: this locks the table!
• Changing column encoding requires a table rebuild
• Zstandard compression encoding, very good for large VARCHAR like
product descriptions, JSON, etc. (Jan’17)
https://aws.amazon.com/about-aws/whats-new/2016/11/amazon-redshift-announces-new-data-compression-connection-management-and-data-loading-
features/
https://aws.amazon.com/about-aws/whats-new/2017/01/amazon-redshift-now-supports-the-zstandard-high-data-compression-encoding-and-two-new-
aggregate-functions/
22. Automatic compression is a good thing (mostly)
“The definition of insanity is doing the same thing over and over again, but
expecting different results”.
- Albert Einstein
If you have a regular ETL process and you use temporary tables or staging
tables, turn off automatic compression
• COMPDUPDATE OFF in COPY command
• Use ANALYZE COMPRESSION to determine the right encodings
• Use CREATE TABLE … LIKE with the appropriate compression setting
23. Automatic compression is a good thing (mostly)
• From the zone maps we know:
• Which blocks contain the range
• Which row offsets to scan
• If SORTKEYs are much more compressed than other
columns:
• Many rows per block
• Large row offset
• Unnecessary I/O
Consider reducing/not using compression on SORTKEYs "
à less SORTKEYs per block"
à smaller offsets"
à finer granularity"
à less I/O

26. Parallelism is a function of load files
Each slice can load one file at a time:
• Streaming decompression
• Parse
• Distribute
• Write
A single input file means "
only one slice is ingesting data
Realizing only partial cluster usage as 6.25% of slices are active
0 2 4 6 8 10 12 141 3 5 7 9 11 13 15
27. Maximize throughput with multiple files
Use at least as many input files as
there are slices in the cluster
With 16 input files, all slices are
working so you maximize
throughput
COPY continues to scale linearly
as you add nodes
0 2 4 6 8 10 12 141 3 5 7 9 11 13 15
29. Statistics
• Amazon Redshift query optimizer relies on up-to-date
statistics
• Statistics are necessary only for data that you are accessing
• Updated stats are important on:
• SORTKEY
• DISTKEY
• Columns in query predicates
30. ANALYZE tables regularly
• After every single load for popular columns
• Weekly for all columns
• Look at SVV_TABLE_INFO(stats_off) for stale stats
• Look at stl_alert_event_log for missing stats
• Look for uncompressed columns
https://docs.aws.amazon.com/redshift/latest/dg/t_Analyzing_tables.html
https://docs.aws.amazon.com/redshift/latest/dg/r_STL_ALERT_EVENT_LOG.html
31. VACUUM tables regularly
• Weekly is a good target
• Number of unsorted blocks is a good indicator
• Look at SVV_TABLE_INFO(unsorted, empty)
• Deep copy might be faster for high percent unsorted
• 20% unsorted or more : usually faster to deep copy
• CREATE TABLE AS
https://docs.aws.amazon.com/redshift/latest/dg/r_VACUUM_command.html
32. WLM queue
• Identify short/long-running queries
and prioritize them
• Define multiple queues to route
queries appropriately
• Default concurrency of 5
• Use wlm_apex_hourly.sql to
tune WLM based on peak
concurrency requirements
Cluster status: commits and WLM
Commit queue
• How long is your commit queue?"
• Identify needless transactions
• Group dependent statements
within a single transaction
• Offload operational workloads
• STL_COMMIT_STATS
