4 months ago The rich indexer feature is currently enabled on a backup CKB node, access address: https://mainnet-ckb-node-01-backup.magickbase.com
However, it should be noted that after turning on the rich indexer feature, it will occupy a certain amount of additional disk space:
# du -sh ./*
51G ./ckb-node-data # CKB main network node data disk occupation
56G ./ckb-rick-index-pgsq-data # indexer pg database data disk occupation

2 months ago @guomaoqiu I can't index anything with the new deployment. Can you help me check if the deployment is working properly?
Please ignore this comment. I forgot that the deployment is in sync with the mainnet instead of the testnet

2 months ago The partial indexing feature takes too long to execute, rendering it unusable in some scenarios. The following request takes over 30 seconds to process, resulting in a 408 HTTP Request Timeout error
This SQL takes about 7-8s to execute

# This file consists of lines of the form:

#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, run "pg_ctl reload", or execute
# "SELECT pg_reload_conf()". Some parameters, which are marked below,
# require a server shutdown and restart to take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.
