Git, Compression, and Deltas - An explanation

Git Compression of Blobs and Packfiles.

Many users of Git are curious about the lack of delta compression at the object (blob) level when commits are first written. This efficiency is saved until the pack file is written. Loose objects are written in compressed, but non-delta format at the time of each commit.

A simple run though of a commit sequence with only the smallest change to the image (in uncompressed TIFF format to amplify the observable behavior) aids the understanding of this deferred and different approach efficiency.

The command sequence:

JDBC_PING with keycloak and postgresql on AWS Fargate
In your effort of implementing standalone-ha with keycloak postgresql using JDBC_PING you will stumble upon many sites that define
the table structure for jgroupsping and the right one goes like this -
CREATE TABLE IF NOT EXISTS JGROUPSPING (
own_addr varchar(200) NOT NULL,
cluster_name varchar(200) NOT NULL,
ping_data BYTEA,
constraint PK_JGROUPSPING PRIMARY KEY (own_addr, cluster_name)
);
