rosbag2_storage_sqlite3

Storage implementation plugin for rosbag2 providing SQLite3 .db3 files as the bag storage backend.

Storage Configuration File

The --storage-config-file option for this plugin takes files in the following format:

read:
  pragmas: <list of SQLite pragma settings for read-only>
write:
  pragmas: <list of SQLite pragma settings for write modes>

By default, SQLite settings are significantly optimized for performance. This might have consequences of bag data being corrupted after an application or system-level crash. This consideration only applies to current bagfile in case bag splitting is on (through --max-bag-* parameters). If increased crash-caused corruption resistance is necessary, use resilient option for --storage-preset-profile setting.

Settings are fully exposed to the user and should be applied with understanding. Please refer to documentation of pragmas.

An example configuration file could look like this:

write:
  pragmas: ["journal_mode = MEMORY", "synchronous = OFF", "schema.cache_size = 1000", "schema.page_size = 4096"]
