Parameters for the participant node's stores
- maxItemsInSqlClause
maximum number of items to place in sql "in clauses"
- maxPruningBatchSize
maximum number of events to prune from a participant at a time, used to break up canton participant-internal batches
- ledgerApiPruningBatchSize
Number of events to prune from the ledger api server index-database at a time during automatic background pruning. Canton-internal store pruning happens at the smaller batch size of "maxPruningBatchSize" to minimize memory usage whereas ledger-api-server index-db pruning needs sufficiently large batches to amortize the database overhead of "skipping over" active contracts.
- pruningMetricUpdateInterval
How frequently to update the
max-event-agepruning progress metric in the background. A setting of None disables background metric updating.- acsPruningInterval
How often to prune the ACS journal in the background. A very high interval will let the journal grow larger and eventually slow queries down. A very low interval may cause a high load on the journal table and the DB. The default is 60 seconds. A domain's reconciliation interval also limits the frequency of background pruning. Setting the pruning interval below the reconciliation interval doesn't not increase the frequency further.
