Currently, Scylla logs a warning when it writes a cell, row or partition which are larger than certain configured sizes. These warnings contain the partition key and in case of rows and cells also the cluster key which allow the large row or partition to be identified. However, these keys can contain user-private, sensitive information. The information which identifies the partition/row/cell is also inserted into tables system.large_partitions, system.large_rows and system.large_cells respectivelly.
This change removes the partition and cluster keys from the log messages, but still inserts them into the system tables.
The logged data will look like this:
Large cells:
WARN 2024-04-02 16:49:48,602 [shard 3: mt] large_data - Writing large cell ks_name/tbl_name: cell_name (SIZE bytes) to sstable.db
Large rows:
WARN 2024-04-02 16:49:48,602 [shard 3: mt] large_data - Writing large row ks_name/tbl_name: (SIZE bytes) to sstable.db
Large partitions:
WARN 2024-04-02 16:49:48,602 [shard 3: mt] large_data - Writing large partition ks_name/tbl_name: (SIZE bytes) to sstable.db
Fixes#18041Closesscylladb/scylladb#18166
This PR removes information about outdated versions, including disclaimers and information when a given feature was added.
Now that the documentation is versioned, information about outdated versions is unnecessary (and makes the docs harder to read).
Fixes https://github.com/scylladb/scylladb/issues/12110Closesscylladb/scylladb#17430
The log warning format has changed since f3089bf3d1
and was fixed in the previous patch to include
a delimiter between the partition key, clustering key, and
column name.
